FIELD

The present disclosure relates to nanolipoprotein particles (NLPs) and, in particular, to nanolipoprotein particles comprising telodendrimers and Chlamydia major outer membrane protein (MOMP) as well as related compositions, methods and systems.

BACKGROUND

Chlamydia is a prevalent sexually transmitted infection that affects over 100 million people worldwide. Although most individuals infected with Chlamydia trachomatis are initially asymptomatic, symptoms can arise if left undiagnosed. Long-term infection can result in debilitating side effects such as pelvic inflammatory disease, infertility, and blindness. Chlamydia infection, therefore, constitutes a significant public health threat and underscores the need for a vaccine.

Chlamydia strains express a major outer membrane protein (MOMP) that is shown to be an effective vaccine antigen. However, in view of poor solubility, low yield and protein misfolding of the Chlamydia MOMP protein production of a functional recombinant MOMP protein for vaccine development has been challenging.

The accompanying drawings, which are incorporated into and constitute a part of this specification, illustrate one or more embodiments of the present disclosure and, together with the detailed description and example sections, serve to explain the principles and implementations of the disclosure. Exemplary embodiments of the present disclosure will become more fully understood from the detailed description and the accompanying drawings, wherein:

FIG. 1A is a grayscale version of a figure from Feher et al. 2013 [1] which shows a schematic representation of the secondary structure and “predicted topology of the C. trachomatis MOMP serovar C monomer.” (see Feher et al. 2013 FIG. 4) (SEQ ID NO: 66) wherein the variable domains are shown by domains with residues in gray circles in the MOMP loops, while transmembrane domains are shown by amino acids within squares.

FIG. 1B is a gray scale version of a figure from Feher et al. [1] which shows a schematic representation of a “MOMP model surface, mapping of VD. Positions attaching the VDs to the barrel mapped (dark) onto the molecular surface of the MOMP trimer model” (see Feher et al. 2013 FIG. 5A legend) wherein the variable domains are designated by the V1-V4 which are known or expected to be important for immunogenicity

FIG. 1C is a gray scale version of a figure from Feher et al. 2013 [1] which shows “MOMP loops 1 and 4 potential inter-monomer stabilizing contacts. Two of the three monomer b-barrels (light gray on the right and dark gray on the left ribbon representation) illustrate the proximity of Loops 1 and 4. Their tryptophan and cysteine residues (space-filling atom representation) on neighboring trimer subunits are shown (C29 not modeled). Residues W252 and W273 are at the exterior membrane interface in the putative aromatic girdle” (see Feher et al. 2013 FIG. 5B legend).

FIG. 1D is a figure from Tu et al. 2014 [2]showing “an homology analysis of MOMP multiepitope Grey shading indicates identical residues, and unshaded indicates non-identical residues) (see Tu et al. 2014, FIG. 1 legend) (SEQ ID NOs: 67 to SEQ ID NO: 70)

FIG. 2 shows a schematic of an exemplary method to prepare mMOMP-tNLP according to an embodiment herein described. FIG. 2 panels (a-c) mMOMP DNA, Δ49ApoA1 DNA, and DMPC lipids/telodendrimer were mixed in a cell free reaction chamber. FIG. 2 panel (d) Protein translation and the self-assembly of mMOMP-tNLPs in a cell free lysate. FIG. 2 panel (e) shows a schematic representation of the assembled mMOMP-tNLP product. As shown in the schematic, the cell-free expression of mMOMP from a DNA construct in presence of Δ49ApoA1 scaffold protein, lipids and telodendrimers results in the formation of a complex of soluble mMOMP in a functional porin structure within a tNLP.

FIG. 3 shows codon optimized and species matched DNA sequences of FIG. 3A shows a comparison of wild type vs. codon optimized mouse nucleic acid sequence for the encoded Δ49ApoA1 gene (SEQ ID NO: 61, SEQ ID NO: 62). FIG. 3B shows a comparison between wild type Chlamydia muridarum MOMP vs. codon optimized MOMP nucleic acid sequence (SEQ ID NO: 64 SEQ ID NO: 65), the asterisk symbol marks where the native sequence and the optimized sequence are the same. The wild type mouse nucleic acid sequence for the encoded Δ49ApoA1 gene is also shown in FIG. 13. The codon optimized mouse nucleic acid sequence for the encoded Δ49ApoA1 gene is also shown in FIG. 14. The wild type Chlamydia muridarum MOMP nucleic acid sequence is also shown in FIG. 16. The codon optimized Chlamydia muridarum MOMP nucleic acid sequence is also shown in FIG. 17.

FIG. 4 shows images of SDS-PAGE gels with separated bands of bodipy (boron dipyrromethene)-labeled mMOMP visualized using a fluorescent imager. The gels show an example of soluble mMOMP production in presence of tNLPs, exemplified by bodipy-labeled mMOMP expressed in a cell-free system. Soluble protein was obtained by centrifuging at 14,100 rcf for 10 minutes and supernatant was collected. The total (T) and soluble (S) portions of the cell-free mixture were resolved by SDS-PAGE then imaged with fluorescent imager. FIG. 4 Panel (a) shows total and soluble portions of mMOMP produced in a cell-free expression system in the presence of DMPC. FIG. 4 Panel (b) shows total and soluble portions of mMOMP produced in a cell-free expression system, co-expressed with Δ49ApoA1 in the presence of DMPC and telodendrimer PEG^(5k)-CA₈. The presence of the mMOMP protein band in the ‘S’ lane of FIG. 4 Panel (b) indicates that the addition of telodendrimers to the cell-free expression system results in soluble mMOMP protein, with the solubility of mMOMP increasing from 10% to 75% upon insertion into tNLP.

FIG. 5 shows examples of expression and purification of mMOMP-tNLP. In particular, FIG. 5 Panel (a) shows a SYPRO Ruby Protein Gel stain of 4-12% SDS-PAGE of nickel affinity chromatography-purified mMOMP-tNLP. Total unpurified lysate (Total), flow through (FT), Washes (W) 1 and 6, and Elutions (E) 1 through 6. All samples were boiled for 5 minutes in the presence of 50 mM DTT. mMOMP is at 40 kDa and the Δ49ApoA1 is at 22 kDa. M: molecular weight marker. The SDS-PAGE gel densitometry analysis of FIG. 5 panel (a) indicates that affinity purified mMOMP-tNLP is 95% pure, and yields 1.5 mg of purified mMOMP-tNLP per 1 mL of cell-free reaction. Distinct bands of mMOMP and Δ49ApoA1 indicate that the two proteins are co-purifying as a complex. FIG. 5 Panel (b) shows a diagram reporting SEC traces of mMOMP-tNLP particles from four nickel affinity column elution fractions (E1, E2, E3 and E4), where the different nickel affinity column fractions show the same SEC elution time, indicating they contain the same sized mMOMP-tNLPs. The elutions in panel A and b are the same elution fractions. X axis represents absorption at 280 nm, whereas Y axis is the time of elution. The SEC analysis of FIG. 5 panel b confirms that each mMOMP-tNLP fraction eluted at the appropriate time (retention time (t_(r))˜7 min) without un-incorporated protein or free lipid peaks (t_(r)˜15 min and 4 min, respectively), indicating that the complex was a homogenous mixture of mMOMP-tNLPs. FIG. 5 Panel (c) shows an image of a dot blot of SEC-purified mMOMP-tNLP samples in duplicate, probed with mAb40 and mAbHIS antibodies. The dot blots of SEC fractions of FIG. 5 panel (c) show apolipoprotein and mMOMP co-localized within the SEC fractions.

FIG. 6 shows examples of size distribution and cryoEM imaging of mMOMP-tNLPs. In particular, FIG. 6 Panel (a) shows the size distribution of empty tNLPs as measured by Dynamic Light Scattering (DLS). FIG. 6 Panel (b) shows the size distribution of mMOMP-tNLPs measured by DLS. The graphs of FIG. 6 panel (a) and panel (b) show empty tNLPs approximately 10 nm in diameter and mMOMP-tNLP particle with an almost 4-fold increase in diameter to about 40 nm. FIG. 6 Panel (c) shows images of cryoEM of mMOMP-tNLP and tNLP, demonstrating that the mMOMP particles are disc like in shape and that there are size differences between tNLP and mMOMP-tNLP particles. Detailed images of the discs show the distribution of mMOMP protein multimers, shown as multiple dark regions of enhanced density within the mMOMP-tNLP particle.

FIG. 7 shows images of mMOMP-tNLPs analyzed by SDS-PAGE and Western blot. In particular, FIG. 7 Panel (a) shows an image of a SYPRO Ruby Protein Gel stain of 4-12% SDS-PAGE of affinity purified mMOMP-tNLP and tNLP alone. mMOMP monomer shows a band at ˜40 kDa and the Δ49ApoA1 shows a band at 22 kDa. The mass ratio of soluble mMOMP to apolipoprotein is ˜2:1. Lane 1 shows a molecular weight marker (M). In lane 2, the protein band pattern indicates that the application of heat and reducing agent have broken down higher order mMOMP structure. In contrast, in lane 3, the presence of higher order bands indicates mMOMP multimer conformation is retained in absence of the application of heat and reducing agent. FIG. 7 Panel (b) shows an image of a Western blot of mMOMP-tNLP and tNLP alone. Shown is a transfer membrane probed with mAb40 (1:1000 dilution). As indicated, samples were incubated at room temperature or were boiled for 5 minutes in the presence of 50 mM DTT. Similar to the results shown in FIG. 7 (a), the Western blot analysis of FIG. 7 panel (b) also indicates the formation of higher order oligomer structures of mMOMP in mMOMP-tNLPS, in absence of heat and denaturant.

FIG. 8 shows exemplary results of dot blot analysis of mMOMP-tNLP and tNLP assemblies treated with heat and reducing agent. The mMOMP-tNLP and tNLP assemblies were blotted in triplicate and probed with mAb40 (linear epitope antibody) and mAbHIS (penta-His antibody). Where indicated, samples were boiled for 5 minutes in the presence of 50 mM DTT. In the illustration of FIG. 8, a same intensity of signal is observed for antibodies specific for mMOMP with and without heat and reducing agent, indicating that heat and DTT do not affect the mAb40 binding to mMOMP, and that oligomers of mMOMP are broken down to monomers upon heat and DTT.

FIG. 9 shows exemplary results of conductance analysis of mMOMP-tNLPs. In particular, FIG. 9 panel (a) shows conductance traces recorded at 50 mV applied voltage in physiological conditions after tNLP alone (i) and mMOMP-tNLPs (ii-iv) were added to the measurement chamber. Current increases seen after mMOMP-tNLP addition indicate pore formation. Representative traces show 1× (ii) and 3× (iii) mMOMP-tNLP incorporations. Trace (iv) shows several incorporations events occurring in quick succession. The increases shown in the traces shown in FIG. 9 panel (a) indicate the formation of bilayer pore formation by mMOMP proteins, indicating functional mMOMP insertion. FIG. 9 Panel (b) shows a histogram of 184 conductance events. Dashed line indicates best fit to a sum of Gaussian peaks for 1× and 3× incorporation events, indicating that the mMOMP channel of FIG. 9 panel (b) have a tendency to oligomerize within the membrane and form trimers (corresponding to three pores).

FIG. 10 shows exemplary results of in vivo testing of mMOMP-tNLPs. In particular, FIG. 10 Panel (a) shows results of ELISA analysis, revealing that mice administered with mMOMP-CpG-tNLPs displayed strong antibody titers compared to mice administered with tNLPs, CpG-tNLPs, or PBS. Sera from mice administered with mMOMP-CpG-tNLPs, CpG-tNLPs, or PBS were loaded on an ELISA plate pre-coated with mMOMP-tNLPs (black dots) or empty tNLPs (grey dots) and antibody titers were measured. FIG. 10 Panel (b) shows images of four western blots, wherein mMOMP protein was loaded onto each lane equally and mouse sera from mice administered with mMOMP-CpG-tNLPs, CpG-tNLPs, Chlamydia EB, or PBS were then incubated with the blot overnight. Lane 1 is blotted with mouse sera immunized with mMOMP-CpG-tNLP and shows significant mMOMP antibody binding. Lane 2 is blotted with mouse sera immunized with CpG-tNLP. Lane 3 is blotted with mouse sera immunized with live Chlamydia EB and confirms that Chlamydia EB induces MOMP antibodies that bind to recombinant mMOMP. The decreased signal from this blot is because Chlamydia EB contains many surface antigens, not just mMOMP, therefore it induces a large variety of antibodies. Lane 4 is blotted with mice sera immunized with PBS control group and shows no mMOMP binding. M: molecular weight marker.

FIG. 11 shows a schematic representation of an exemplary telodendrimer suitable to be included in MOMP-tNLPs herein described.

The MOMP-NLP and NLP assemblies were blotted in triplicate and probed with mAb40, mAbHIS and mAb18b. Addition of heat and DTT results in a decrease in signal as detected by mAb18b, a conformational trimer recognition antibody, indicating a loss in trimer formation. mAb40 recognizes both MOMP monomer and trimer as it binds to a linear epitope. The mAbHIS recognizes the HIS tag on the Δ49A1 protein. FIG. 22 panel C shows conductance traces recorded at 50 mV applied voltage in physiological conditions after NLP alone and MOMP-NLP were added to the measurement chamber.

DETAILED DESCRIPTION

Provided herein are nanolipoprotein particles comprising telodendrimers and Chlamydia major outer membrane protein (MOMP) and related compositions methods and systems.

The term “nanolipoprotein particle” “nanodisc” “rHDL” or “NLP” as used herein indicates a supramolecular complex formed by a membrane forming lipid arranged in a lipid bilayer stabilized by a scaffold protein. The membrane forming lipids and scaffold protein are components of the NLP. In particular, the membrane forming lipid component is part of a total lipid component, (herein also membrane lipid component or lipid component) of the NLP together with additional lipids such as functionalized lipids and/or lysolipids, that can further be included in the NLPs as will be understood by a skilled person upon reading of the present disclosure. The scaffold protein component is part of a protein component of the NLP together with additional proteins such as membrane proteins, target proteins and other proteins that can be further included as components of the NLPs as will be understood by a skilled person upon reading of the present disclosure. Additional components can be provided as part of the NLP herein described as will be understood by a skilled person. In particular, the membrane lipid bilayer can attach membrane proteins or other amphipathic compounds through interaction of respective hydrophobic regions with the membrane lipid bilayer. The membrane lipid bilayer can also attach proteins or other molecule through anchor compounds or functionalized lipids as will be understood by a skilled person upon reading of the disclosure. In a nanolipoprotein particle, the membrane lipid bilayer can be confined in a discoidal configuration by the scaffold protein. Predominately discoidal in shape, nanolipoprotein particles typically have diameters between 5 to 25 nm, share uniform heights between 3 to 6 nm and can be produced in yields ranging between 30 to 90%.

In particular, in embodiments herein described the nanolipoprotein particle can be formed by a lipid bilayer confined in a discoidal configuration by a scaffold protein. In this configuration, the lipid bilayer confined by the scaffold protein can be 3-6 nanometers in thickness, the nanolipoprotein particle can have an overall diameter of 5-25 nanometers, and the scaffold protein on the particle can have a thickness of 1-2 nanometers. In some embodiments, an entire NLP structure can be up to 600 kilodaltons in weight.

The particular membrane forming lipid, scaffold protein, the lipid to protein ratio, and the assembly parameters determine the size and homogeneity of nanolipoprotein particles as will be understood by a skilled person. In the nanolipoprotein particle the membrane forming lipid are typically arranged in a membrane lipid bilayer confined by the scaffold protein in a discoidal configuration as will be understood by a skilled person.

The term “membrane forming lipid” or “amphipathic lipid” as used herein indicates a lipid possessing both hydrophilic and hydrophobic moieties that in an aqueous environment assembles into a lipid bilayer structure that consists of two opposing layers of amphipathic molecules known as polar lipids. Each polar lipid has a hydrophilic moiety, i.e. a polar group such as, a derivatized phosphate or a saccharide group, and a hydrophobic moiety, i.e., a long hydrocarbon chain. Exemplary polar lipids include phospholipids, sphingolipids, glycolipids, ether lipids, sterols, alkylphosphocholines and the like. Amphipathic lipids include but are not limited to membrane lipids, i.e. amphipathic lipids that are constituents of a biological membrane, such as phospholipids like dimyristoylphosphatidylcholine (DMPC) or dioleoylphosphoethanolamine (DOPE) or dioleoylphosphatidylcholine (DOPC), or dipalmitoylphosphatidylcholine (DPPC). In a preferred embodiment, the lipid is dimyristoylphosphatidylcholine (DMPC).

The term “scaffold protein” as used herein indicates any amphipathic protein that is capable of self-assembly with amphipathic lipids in an aqueous environment, organizing the amphipathic lipids into a bilayer disc, and comprise apolipoproteins, lipophorins, derivatives thereof (such as truncated and tandemly arrayed sequences) and fragments thereof (e.g. peptide fragments and synthetic peptides) which maintains the amphipathic nature and capability of self-assembly, such as apolipoprotein E4 (22Kd fragment), lipophorin III, apolipoprotein A-1 and the like. In general, scaffold proteins have an alpha helical secondary structure in which a plurality of hydrophobic amino acids form a hydrophobic face and a plurality of hydrophilic amino acids form an opposing hydrophilic face. In some embodiments, rationally designed amphipathic peptides and synthetic apolipoproteins which maintain an amphipathic structure and capability of self-assembly can serve as a scaffold protein of the NLP.

The term “apolipoprotein” as used herein indicates an amphipathic protein that binds lipids to form lipoproteins. The term “amphipathic” pertains to a molecule containing both hydrophilic and hydrophobic properties. Exemplary amphipathic molecules comprise molecules having hydrophobic and hydrophilic regions/portions in its structure. Examples of biomolecules which are amphipathic include but not limited to phospholipids, cholesterol, glycolipids, fatty acids, bile acids, saponins, and additional lipids identifiable by a skilled person. A “lipoprotein” as used herein indicates a biomolecule assembly that contains both proteins and lipids. In particular, in lipoproteins, the protein component surrounds or solubilizes the lipid molecules enabling particle formation. Exemplary lipoproteins include the plasma lipoprotein particles classified under high-density (HDL) and low-density (LDL) lipoproteins, which enable fats and cholesterol to be carried in the blood stream, the transmembrane proteins of the mitochondrion and the chloroplast, and bacterial lipoproteins. In particular, the lipid components of lipoproteins are insoluble in water, but because of their amphipathic properties, apolipoproteins such as certain Apolipoproteins A and Apolipoproteins B and other amphipathic protein molecules can organize the lipids in a bilayer orientation with exposed hydrophilic moieties, creating the lipoprotein particle that is itself water-soluble, and can thus be carried through water-based circulation (e.g. blood, lymph in vivo or in vitro). Apolipoproteins known to provide the protein components of the lipoproteins can be divided into six classes and several sub-classes, based on the different structures and functions.

In embodiments herein described the nanolipoprotein particles further comprise a Chlamydia major outer membrane protein (MOMP).

The term “Chlamydia” as used herein indicates a genus of pathogenic bacteria of the phylum Chlamydiae that are obligate intracellular bacteria as well as the bacteria belonging to said genus. Chlamydia bacteria are ovoid in shape and stain Gram-negative. Chlamydia bacteria are characterized by a developmental cycle involving an infectious elementary body (EB) and the vegetative reticulate body (RB). In particular, the EB remains within a phagosome after Chlamydia attaches and promotes entry into a target host cell. The EB differentiates into the RB which then redifferentiate into EB after several rounds of replication. The EB is small, dense, rigid, metabolically inert, and resistant to the hostile extracellular environment while the RB is large, low-density, less rigid, metabolically active but noninfectious (Moulder, J. W., Hatch, T. P., Kuo, C.-C., Schachter, J., and Storz, J. 1984. Order II: Chlamydiales. In Bergey's manual of systematic bacteriology, Vol. 1 (eds. N. R. Krieg and J. G. Holt), pp. 729-739. Williams & Wilkins, Baltimore, Md.). Chlamydia comprise Chlamydia species Chlamydia trachomatis, Chlamydia pneumoniae, and Chlamydia psittaci (human pathogens), Chlamydia suis (affects only swine), Chlamydia pecorum (affects cows/swine/koala) and Chlamydia pneumonia (affects koala) and Chlamydia muridarum (affects only mice and hamsters)

The term “MOMP” as used herein indicates the major outer membrane protein of a bacterium of the genus Chlamydia capable of folding into a beta barrel structure that can associate with other MOMP proteins. MOMP can be encoded by the gene ompA of bacteria of the Chlamydia genus. Typically, a MOMP beta barrel structure consists of 18 transmembrane regions. In general, MOMP has a molecular mass of ˜40 kDa and can make up 60% of total outer membrane protein. Chlamydial MOMP is detectable both in the EB and in the RB of Chlamydia with techniques such as monoclonal antibodies (MAbs) and surface radioiodination as well as additional techniques identifiable by a skilled person. MOMPs comprise proteins with low solubility (from 0% to 50% of the total amount of MOMP protein in the mixture). In particular, MOMP can have a solubility score lower or equal to 20% and in some instances a solubility of 10% or lower.

MOMP has been identified to be a porin even if MOMP has been associated with other functions such as a potential chlamydial cytoadhesin as well as a structural protein. Porins are a family of membrane channels commonly found in the outer membranes of Gram-negative bacteria, where they serve as diffusion pathways for nutrients, waste products, and antibiotics and can also be receptors for bacteriophages. Porins have a structural topology comprised of antiparallel β-strands spanning the outer membrane, a water-filled inner channel, tight β-turns extending into the periplasmic region and flexible loops reaching beyond the extracellular surface [1]. The MOMP of Chlamydia genus contains four symmetrically spaced variable domains (VDs 1 to 4). The variable domain regions are predicted to be outside the transmembrane β-strands. Detailed structural description of MOMP of Chlamydia can be found in Feher et al. 2014 [1].

MOMP in the sense of the disclosure encompasses a protein from a Chlamydia bacterium capable of oligomerization, formation of homo-trimers and functional porins, and capable of forming antigens that can elicit an immune response. In some embodiments, MOMP comprised in tNLPs described herein primarily forms homo-trimers [3].

MOMP in the sense of the disclosure encompass MOMP proteins of various bacteria within the Chlamydia genus as well as species-specific variants of MOMP, such as a MoPn MOMP protein (mMOMP), a type of MOMP expressed in the mouse-specific bacterium Chlamydia muridarum,

In some embodiments, the MOMP-NLPs herein described can include one or more MOMP fragments alone or in combination with MOMP protein. The term “MOMP fragment” is a portion of a MOMP protein herein described comprising a transmembrane region including for example MOMP hydrophobic amino acid configured to interact with a membrane lipid bilayer. In a MOMP fragment, the transmembrane region can be formed by at least one transmembrane domain each domain comprising 3 to 40 hydrophobic amino acid residues.

Additional sequences of the ompA gene and MOMP protein or fragments thereof are recognizable by persons skilled in the art, comprising sequences of members of the Chlamydia genus such as Chlamydia trachomatis, Chlamydia muridarum and Chlamydia suis and in particular the fifteen known Chlamydia trachomatis serovars and additional strains known to those skilled in the art, which can be found in public databases such as NCBI.

In particular, C. trachomatis includes three human biovars: (1) Serovars Ab, B, Ba, or C, which cause trachoma: infection of the eyes, which can lead to blindness, (2) Serovars D-K, which cause urethritis, pelvic inflammatory disease, ectopic pregnancy, neonatal pneumonia, and neonatal conjunctivitis, and (3) Serovars L1, L2, and L3, which cause lymphogranuloma venereum.

The term “biovar” as used herein refers to a variant prokaryotic strain that differs physiologically and/or biochemically from other strains in a particular species. The term “serovar” refers to strains that have antigenic properties that differ from other strains.

In some embodiments, additional ompA genes and MOMP proteins can be identified by conducting homology search of gene or protein sequences in databases such as NCBI and others known to persons skilled in the art.

Homology can be determined using available sequence analysis algorithm programs including but not limited to CLUSTAL, ALIGN, GAP, BESTFIT, BLAST, FASTA, and TFASTA among others known to a skilled person. Sequences of DNA, mRNA, or protein having at least 50% sequence identity to known ompA DNA and mRNA sequences and MOMP protein sequences can be considered homologous. The term “percent identity” refers to a quantitative measurement of the similarity between sequences of a polypeptide or a polynucleotide and, in particular, indicates the amount of characters that match between two different sequences. The similarity between sequences is typically measured by a process that comprises the steps of aligning the two polypeptide or polynucleotide sequences to form aligned sequences, then detecting the number of matched characters, i.e. characters similar or identical between the two aligned sequences, and calculating the total number of matched characters divided by the total number of aligned characters in each polypeptide or polynucleotide sequence, including gaps. The similarity result is expressed as a percentage of identity.

Homology can also be determined on the basis of protein structural similarity. Several publicly available online servers can be used to detect protein structure alignment and calculate percent structural similarity, such as FATCAT, SuperPose, iPBA, MAPSCI, and others known to a person skilled in the art. Proteins having at least 50% structural identity to known MOMP protein structures or fragments thereof can be considered homologous.

MOMP in the sense of the disclosure also includes codon-optimized sequences of MOMP expressed in a cell-free expression system, herein exemplified by an E. coli cell-free expression system (see e.g. the sequences illustrated in FIG. 3 and the sequences illustrated in FIGS. 12C, 16 and 17). Additional MOMP variants comprise MOMPs having a sequence that differs in all or in part from a naturally occurring MOMP and that maintain the beta barrel structure with the 18 transmembrane regions separated by loops. In particular, additional MOMP variants include modifications with respect to a natural MOMP protein which maintain the barrel structure while changing the level of immunogenicity of the MOMP. In some of these embodiments, the difference in sequence between a natural MOMP and the variant can be localized in the extra cellular loops.

MOMP in the sense of the present disclosure comprise wild type MOMP and MOMP derivatives such as MOMP including mutations, deletions, truncations and MOMP fusion protein including MOMP fused with other peptides.

In some embodiments, the MOMP in the sense of the present disclosure can be recombinant forms of MOMP in which the MOMP coding sequence has been mutated to present a unique DNA sequence, which does not alter the amino acids to enhance transcription and translation of the target protein. Exemplary sequences are shown in the illustration of FIG. 3 and are also shown in FIGS. 16 and 17. The exemplary mMOMP gene of FIG. 3 (also shown in FIG. 17) provide an E. coli codon-optimized version of MOMP expressed in the mouse-specific Chlamydia muridarum. The exemplary MoPn gene and protein sequences of FIG. 12C provide an E. coli codon-optimized version of MOMP expressed in the mouse-specific Chlamydia muridarum MoPn.

As would be understood by those skilled in the art, the term “codon optimization” as used herein refers to the introduction of synonymous mutations into codons of a protein-coding gene in order to improve protein expression in expression systems of a particular organism, such as E. coli in accordance with the codon usage bias of that organism. The term “codon usage bias” refers to differences in the frequency of occurrence of synonymous codons in coding DNA. The genetic codes of different organisms are often biased towards using one of the several codons that encode a same amino acid over others—thus using the one codon with, a greater frequency than expected by chance. Optimized codons in microorganisms, such as Escherichia coli or Saccharomyces cerevisiae, reflect the composition of their respective genomic tRNA pool. The use of optimized codons can help to achieve faster translation rates and high accuracy.

In the field of bioinformatics and computational biology, many statistical methods have been proposed and used to analyze codon usage bias. Methods such as the ‘frequency of optimal codons’ (Fop), the Relative Codon Adaptation (RCA) or the ‘Codon Adaptation Index’ (CAI) are used to predict gene expression levels, while methods such as the ‘effective number of codons’ (Nc) and Shannon entropy from information theory are used to measure codon usage evenness. Multivariate statistical methods, such as correspondence analysis and principal component analysis, are widely used to analyze variations in codon usage among genes. There are many computer programs to implement the statistical analyses enumerated above, including CodonW, GCUA, INCA, and others identifiable by those skilled in the art. Codon optimization has applications in designing synthetic genes and DNA vaccines. Several software packages are available online for codon optimization of gene sequences, including those offered by companies such as GenScript, EnCor Biotechnology, Integrated DNA Technologies, ThermoFisher Scientific, among others known those skilled in the art. Those packages can be used in providing MOMP with codon ensuring optimized expression in various cell systems as will be understood by a skilled person.

In particular, MOMP in the sense of the disclosure can comprise monomeric or multimeric MOMP such as dimeric and trimeric MOMP.

In some embodiments, MOMP-t-NLPs herein described comprise multimeric MOMP (>2 membrane proteins) embedded in nanoparticles.

In particular, in those embodiments, the peptides and/or synthetic apolipoprotein are configured and selected to provide the a plurality of helical segments each having a primary structure configured to form an alpha helix secondary structure, In the alpha helix secondary structure of at least one helical segment, the peptides and/or synthetic apolipoprotein comprise a plurality of hydrophobic amino acids and a plurality of hydrophilic amino acids positioned in the primary structure to provide an amphipathic alpha helix secondary structure, with the plurality of hydrophobic amino acids forming an hydrophobic amino acid cluster and the plurality hydrophilic amino acids forming an hydrophilic amino acid cluster. In some of those embodiments, the scaffold proteins can be peptides derived from apolipoproteins, and can contain amino acid additions, deletions, or substitutions. In other embodiments, these peptides have no sequence homology to apolipoproteins but can be structural analogs. In some embodiments, the peptides can be prepared with L- or D-amino acids. In embodiments where the scaffold protein comprises one or more peptides the skilled person would be able to identify the ratios of peptides based on the length and number of peptides and apolipoproteins and on a desired dimension of the nanolipoprotein particles upon reading of the present disclosure.

The term “functionalized amphipathic compounds” in the sense of the disclosure indicates compounds having a hydrophobic portion and a hydrophilic portion in a configuration where the hydrophobic portion anchor is able to anchor the compound to the lipid bilayer of the NLP and the hydrophilic portion is presented on the NLP bilayer face following NLP assembly. In the functionalized amphipathic compounds in the sense of the disclosure the hydrophilic portion of typically essentially consists of or comprises a hydrophilic functional group.

The term “functional group” as used herein indicates specific groups of atoms within a molecular structure that are responsible for a characteristic chemical reaction of that structure. Exemplary functional groups include hydrocarbons, groups containing double or triple bonds, groups containing halogen, groups containing oxygen, groups containing nitrogen and groups containing phosphorus and sulfur all identifiable by a skilled person.

The term “present” as used herein with reference to a compound or functional group indicates attachment performed to maintain the chemical reactivity of the compound or functional group as attached. Accordingly, a functional group presented on an amphipathic compound, is able to perform under the appropriate conditions the one or more chemical reactions that chemically characterize the functional group.

The use of functionalized amphipathic compounds enables attachment of various peptides or other biologics to the surfaces of the lipid of the NLP that allows some desired target features to be obtained, such as stability, affinity for a target molecule, and the like. Non-limiting examples of functional groups presented on functionalized lipids include: chelated Ni atoms, azide, anhydride, alkynes, thiols, halogens, carboxy, amino, hydroxyl, and phosphate groups, and additional groups identifiable by a skilled person upon reading of the present disclosure.

In some embodiments, the functional group on the functionalized amphipathic compound can be a reactive chemical groups (e.g. azide, chelated nickel, alkyne, and additional reactive chemical groups identifiable by a skilled person), a biologically active compound (e.g. DNA, peptide, carbohydrate, and additional biologically active group identifiable by a skilled person) or a small molecule (e.g. cellular targeting compound, adjuvant, drug, and additional small molecules identifiable by a skilled person). In some embodiments, the functionalized amphipathic compound is a functionalized lipid compound. Functional groups that enhance the lipid solubility are referred to as hydrophobic or lipophilic functional groups. Functional groups that lack the ability to either ionize or form hydrogen bonds tend to impart a measure of lipid solubility to a drug molecule. The functional group can be attached to the lipid polar head through covalent or ionic bonds and “weak bonds” such as dipole-dipole interactions, the London dispersion force and hydrogen bonding, preferably covalent. Moreover, functionalization of the lipid can involve hydrophobic quantum dots embedded into the lipid bilayer. The following article is incorporated by reference in its entirety: R. A. Sperling, and W. J. Parak. “Surface modification, functionalization and bioconjugation of colloidal inorganic nanoparticles”. Phil. Trans. R. Soc. A 28 Mar. 2010 vol. 368 no. 1915 1333-1383 [4].

In some embodiments, functionalized amphipathic compounds can comprise one or more of 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine-N-(6-((folate)amino)hexanoyl), 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine-N-(6-azidohexanoyl), 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine-N-(succinyl), 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine-N-(succinyl), 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine-N-(glutaryl), 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine-N-(glutaryl), 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine-N-(dodecanyl), 1,2-Dipalmitoyl-sn-Glycero-3-Phosphoethanolamine-N-(hexanoylamine), 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine-N-(dodecanylamine), 1,2-Dipalmitoyl-sn-Glycero-3-Phosphothioethanol, 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine-N-[4-(p-maleimidomethyl)cyclohexane-carboxamide], 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine-N-[4-(p-maleimidophenyl)butyramide], 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine-N-[3-(2-pyridyldithio)propionate], 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine-N-(biotinyl), 1,2-Dioleoyl-sn-Glycero-3-Phospho(Ethylene Glycol), 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine-N-lactosyl, 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[dibenzocyclooctyl(polyethylene glycol)-2000], 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[succinyl(polyethylene glycol)-2000], 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[carboxy(polyethylene glycol)-2000], 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[maleimide(polyethylene glycol)-2000], 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[PDP(polyethylene glycol)-2000], 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[amino(polyethylene glycol)-2000], 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[biotinyl(polyethylene glycol)-2000], 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[cyanur(polyethylene glycol)-2000], 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[folate(polyethylene glycol)-2000], cholesterol modified oligonucleotides, cholesterol-PEG2000-azide, cholesterol-PEG2000-Dibenzocyclooctyl, cholesterol-PEG2000-maleimide, cholesterol-PEG2000-N-hydroxysuccinimide esters, cholesterol-PEG2000-thiol, cholesterol-azide, cholesterol-Dibenzocyclooctyl, cholesterol-maleimide, cholesterol-N-hydroxysuccinimide esters, cholesterol-thiol, C18 modified oligonucleotides, C18-PEG2000-azide, C18-PEG2000-Dibenzocyclooctyl, C18-PEG2000-maleimide, C18-PEG2000-N-hydroxysuccinimide esters, C18-PEG2000-thiol, C18-azide, C18-Dibenzocyclooctyl, C18-maleimide, C18-N-hydroxysuccinimide esters, C18-thiol.

In some embodiments, the MOMP-telo-nanolipoprotein particles herein described can further comprise one or more membrane proteins herein also indicated as target protein. The term “membrane protein” as used herein indicates any protein having a structure that is suitable for attachment to or association with a biological membrane or biomembrane (i.e. an enclosing or separating amphipathic layer that acts as a barrier within or around a cell). In particular, membrane proteins include proteins that contain large regions or structural domains that are hydrophobic (the regions that are embedded in or bound to the membrane); those proteins can be difficult to work with in aqueous systems, since when removed from their normal lipid bilayer environment those proteins tend to aggregate and become insoluble.

Methods and systems for production of MOMP-t-NLPs are also described. In the methods and systems herein described expression of MOMP and the scaffold protein of a MOMP-t-NLP herein described is performed in a cell-free method/system in presence of other NLPs components for a time and under conditions that allow assembly of the NLP.

The membrane forming lipid and the protein components of the MOMP-t-NLP are generally able to self-assemble in a biological (largely aqueous) environment according to the thermodynamics associated with water exclusion (increasing entropy) during hydrophobic association. In the methods and systems herein provided, the amphipathic lipid and the protein components of the NLP are allowed to assembly in a cell free expression system.

As used herein, the wording “cell free expression”, “cell free translation”, “in vitro translation” or “IVT” refer to at least one compound or reagent that, when combined with a polynucleotide encoding a polypeptide of interest, allows in vitro translation of said polypeptide/protein of interest.

The term “polynucleotide” as used herein indicates an organic polymer composed of two or more monomers including nucleotides, or analogs thereof. The term “nucleotide” refers to any of several compounds that consist of a ribose (ribonucleotide) or deoxyribose (deoxyribonucleotides) sugar joined to a purine or pyrimidine base and to a phosphate group, and that are the basic structural units of nucleic acids. The term “nucleotide analog” refers to a nucleotide in which one or more individual atoms have been replaced with a different atom with a different functional group. Accordingly, the term polynucleotide includes nucleic acids of any length of DNA or RNA analogs and fragments thereof. A polynucleotide of three or more nucleotides is also called nucleotidic oligomers or oligonucleotide.

In particular, co-expression of both scaffold protein and MOMP in presence of phospholipids with or without surfactant/detergent can be performed in a “one-pot” reaction that generates, in situ, both scaffold protein and target membrane protein; NLP self-assembly will ensue using phospholipids already in the reaction mixture.

In some embodiments, the additives used in the cell free reaction systems include any substance that improves the solubilization of the protein of interest and/or of any other protein components that are present in the reaction mixtures, any substance that may augment protein production and any substance that improves protein functions. Those additives include but are not limited to cofactors (e.g. retinal, heme) other proteins that facilitate modification (e.g. glycosylases, phosphatases, chaperonins) lipids, redox factors, detergents and protease inhibitors, and in particular, phospholipids such as dimyristoylphosphatidyl choline (DMPC) and the like, and surfactants/detergents such as cholate, triton X-100 and the like. Exemplary detergents that can be used for protein solubilization in the methods and systems herein disclosed, include Heptanoyl-N-methyl-glucamide, Octanoyl-N-methyl-glucamide, Nonanoyl-Nmethyl-glucamide, n-Nonyl-b-D-gluco-pyranoside, N-Octyl-b-D-glucopyranoside, Octyl-b-D-thiogluco-pyranoside, NN-Dimethyldodecylamine-N-oxide and Glycerol. Additional additives that might be included in the reaction mixtures include labels and labeling molecule that can be used to label or tag the target protein and thus to enable the detection of the target protein through detection of a related labeling signal.

The terms “label” and “labeled molecule” as used herein refer to a molecule capable of detection, including but not limited to radioactive isotopes, fluorophores, chemiluminescent dyes, chromophores, enzymes, enzymes substrates, enzyme cofactors, enzyme inhibitors, dyes, metal ions, nanoparticles, metal sols, ligands (such as biotin, avidin, streptavidin or haptens) and the like. The term “fluorophore” refers to a substance or a portion thereof which is capable of exhibiting fluorescence in a detectable image. As a consequence, the wording “labeling signal” as used herein indicates the signal emitted from the label that allows detection of the label, including but not limited to radioactivity, fluorescence, chemoluminescence, production of a compound in outcome of an enzymatic reaction and the like.

In some embodiments, the polynucleotides encoding MOMP and/or the scaffold protein or other proteins can comprise an engineered polynucleotide designed such that the resulting protein can be expressed as a full-length protein. In some embodiments, the polynucleotide is an engineered polynucleotide designed to encode a protein fragment. Protein fragments include one or more portions of the protein, e.g. protein domains or subdomains. In some embodiments, the polynucleotide is an engineered polynucleotide designed to encode a mutated MOMP. In particular, in some embodiments the polynucleotide can also be designed such that the resulting protein, protein fragment or mutated MOMP is expressed as a fusion, or chimeric protein product (i.e. it is joined via a peptide bond to a heterologous protein sequence of a different protein), for example to facilitate purification or detection. A chimeric product can be made by ligating the appropriate nucleic acid sequences encoding the desired amino acid sequences to each other using standard methods and expressing the chimeric product. In particular, in some embodiments, the polynucleotide can be engineered so that the MOMP is labeled or tagged. Labeling or tagging can be performed with methods that include, for example, FRET pairs, NHS-labeling, fluorescent dyes, and biotin as well as coding for a “His-tag” to enable protein isolation and purification via established Ni-affinity chromatography.

In some embodiments herein described, the polynucleotide is a DNA molecule that can be in a linear or circular form, and encodes the desired polypeptide under the control of a promoter specific to an enzyme such as an RNA polymerase, that is capable of transcribing the encoded portion of the DNA.

In embodiments where the polynucleotide is DNA, the DNA may be transcribed as part of the cell free reactions or system. In those embodiments, the DNA contains appropriate regulatory elements, including but not limited to ribosome binding site, T7 promoter, and T7 terminator, and the reagents or compounds include appropriate elements for both transcription and translation reactions. In other embodiments where the polynucleotide is RNA, the RNA can be prepared prior to addition to the cell free reactions/system, wherein the polypeptide of interest is produced, and the reagents or compounds include appropriate elements for translation reactions only.

Accordingly, as used herein, the term “cell free expression”, “cell free translation”, “in vitro translation” or “IVT” refer to methods and systems wherein the transcription and translation reactions are carried out independently, and to systems in which the transcription and translation reactions are carried out simultaneously in a non-cellular compartment, e.g. glass vial.

In each of these methods and systems, the reagents or compounds typically include a cell extract capable of supporting in vitro transcription and/or translation as appropriate. In any case, the cell extracts contain all the enzymes and factors to carry out the intended reactions, and in addition, be supplemented with amino acids, an energy regenerating component (e.g. ATP), and cofactors, including factors and additives that support the solubilization of the protein of interest.

These systems are known in the art and can be identified by the skilled person upon reading of the present disclosure, and exist for both eukaryotic and prokaryotic applications. Exemplary cell free expression systems that can be used in connection with the methods and systems of the present disclosure includes but are not limited to commercial kits for various species such as extracts available from Invitrogen, Ambion, Qiagen and Roche Molecular Diagnostics, cellular extracts made from E. coli or wheat germ or rabbit reticulocytes, or prepared following protocols, such as published laboratory protocols, identifiable by a skilled person upon reading of the present disclosure.

In some embodiments, the cell free system can operate in batch mode or in a continuous mode. In the batch mode, the reaction products remain in the system and the starting materials are not continuously introduced. Therefore, in batch mode, the system produces a limited quantity of protein. In a continuous mode instead, the reaction products are continuously removed from the system, and the starting materials are continuously restored to improve the yield of the protein products and therefore the system produces a significantly greater amount of product.

In some embodiments, MOMP-t-NLPs herein described can be assembled by a translation method, where self-assembly of the NLPs can be achieved while the apolipoprotein or other scaffold protein is provided as a protein in a mixture also comprising one or more membrane forming lipids, one or more telodendrimers, a polynucleotide coding for the MOMP and/or a MOMP fragment, and a scaffold protein. In some embodiments, the scaffold protein to telodendrimer mass ratio can be 15:1 to 1:1, preferably 5:1. In some embodiments, scaffold protein to lipids mass ratio can be 1.5:1 to 0.1:1, preferably 0.5:1. In some embodiments, scaffold protein to lipids mass ratio will be reduced when MOMP is inserted and may be altered to 1.5:0.75 to 0.1:0.75, preferably 0.5:0.75

In some embodiments, MOMP-t-NLPs herein described can be assembled by a translation method, where self-assembly of the NLPs can be achieved while the apolipoprotein or other scaffold protein is being translated from mRNA as described for example in [5-7]. In this process, expression system lysates are mixed with the lipid and telodendrimer component of the NLP and plasmid DNA encoding the scaffold protein. The reaction can then be allowed to proceed until assembly occurs during apolipoprotein expression (e.g. for approximately 4-24 hrs). The apolipoprotein typically contains an affinity tag (e.g. His-tag) for subsequent purification of the self-assembled NLP from the lysate.

In some embodiments, the ratio of lipid to telodendrimer to be added during the assembly process is 1:1 (W/W) to 1:100 (W/W). In some embodiments, the ratio of DNA encoding MOMP and/or a MOMP fragment to DNA encoding scaffolding protein is between 1:1 (W/W) to 200:1 (W/W). Preferably, the ratio of lipid to telodendrimer to be added during the assembly process is 10:1 (W/W). Preferably, the ratio of DNA encoding MOMP and/or a MOMP fragment to DNA encoding scaffolding protein is between 5:1 to 50:1, more preferably between 10:1 to 25:1.

In some embodiments, wherein the MOMP-NLP comprises a MOMP-fragment the ratio of plasmids (pApo:pMOMP-fragment) can be varied in the cell free reaction to control the amount of fragmented MOMP made and inserted during the assembly process. Normally, we use is 1:1 (W/W) to 1:250 (W/W).

In some embodiments, telodendrimers concentrations can be optimized for a MOMP and/or a MOMP fragment by mixing them with lipids at concentrations from 0.5-10 mg (telodendrimer) and 5-60 mg (lipid) per mL. In some embodiments, the telodendrimer and lipid concentration can be at a 2 mg (telodendrimer) and 20 mg (lipid) per mL prior to addition to the cell-free reaction. In some of those embodiments, the MOMP and/or MOMP fragment assembled in the NLPs form tertiary structures recognized using a conformational antibody, which has never been seen with other recombinant forms of MOMP.

In some embodiments, the methods and systems herein described are performed at predefined lipid protein ratio, assembly conditions and/or with the use of preselected protein component (formed by MOMP and Scaffold protein as polynucleotide) and lipid component (formed by Lipid and telodendrimers) so as to increase the yield, control the size and composition of the resulting NLP, provide an NLP of pre-determined dimensions, achieve desired functionality of the NLP, such as a certain level of loading capacity for a target molecule. In some embodiments, the molar ratio of lipid component to scaffold protein component is 10:1, 20:1, 30:1, 40:1, 50:1, 60:1, 70:1, 80:1, 90:1, 100:1, 110:1, 120:1, 130:1, 140:1, 150:1, 160:1, 170:1, 180:1, 190:1, 200:1, 210:1, 220:1, 230:1, and 240:1. In NLPs herein described, the lipid to scaffold protein component ratio can be determined on a case by case basis in view of the experimental design as will be understood by a skilled person.

In some embodiments, the scaffold protein is selected to define the size of empty NLPs. In particular, the scaffold protein and/or the membrane forming lipid can be selected so that the scaffold protein and the membrane forming lipid are contacted at a mass ratio of scaffold protein to membrane forming lipid from about 1:10 to about 1:1 to provide a particle having a size from 10 to 60 nm. In some embodiments, Lipophorin III lipoproteins may assemble into larger NLPs with diameters 10-30 nm range, apolipoprotein A1 NLPs range in size from 10-25 nm, truncated Δ(1-49)Apolipoprotein A1 15-35 nm. Adjustment of protein to lipid ratios by increasing lipid will also increase the size of the NLP. An exemplary, procedure is illustrated in the examples section. Inclusion of MOMP protein can cause up to 4-fold increase in size to the dimensions of an empty NLP.

In some embodiments, the method to assemble MOMP-t-NLPs herein described results in increasing MOMP to achieve detectable MOMP solubility. In particular, solubility can be measured by centrifuging the total cell-free mixtures following completion of the cell free reaction (e.g. by a table centrifuge at max speed for 10 minutes). After centrifugation, the supernatant is collected and MOMP solubility calculated as ratio of the amount MOMP protein in supernatant to the amount of MOMP protein in the total mixture. A percentage solubility can be the calculated by calculating the amount of the MOMP present in the supernatant (e.g. in term of molar concentration or mass concentration.

In particular, in some embodiments, a detectable solubility for recombinant or native MOMP can be achieved without the need of adding detergents. In particular, in some embodiments, no exogenously added detergent is required for solubilization of MOMP to a detectable solubility. In some embodiments, the increased levels of MOMP solubility are detectable with formation of NLPs within the cell free reaction.

In some embodiments, the method to assemble MOMP-t-NLPs herein described results into as high as 8:1 MOMP membrane protein and/or MOMP fragment insertion ratio to NLP, which has not been achieved previously.

In particular in some embodiments, wherein the MOMP-NLP comprises MOMP fragment, the NLP to MOMP ratio is expected to be between 1:1 and 1:25 (Apo:MOMP protein) depending on the fragment size.

In some embodiments, the method to assemble MOMP-t-NLPs herein described results in a MOMP protein and/or a MOMP fragment with a greater than 2 mg/mL of >85% purity without need of using affinity or solubilization tags directly encoded on the MOMP protein.

In some embodiments, the formulation resulting from method to assemble MOMP-t-NLPs herein described in a form susceptible to lyophilization and resolubilization, which result in MOMP-tNLPs that were intact and functional. Accordingly, in some embodiments, the method to assemble MOMP-t-NLPs herein described, the combination of the materials used therein provide stabilized MOMP-t-NLPs.

In some embodiments, any of the MOMP-t-NLP herein described can be comprised in a composition together with a suitable vehicle. The term “vehicle” as used herein indicates any of various media acting usually as solvents, carriers, binders or diluents of a MOMP-t-NLP comprised in the composition as an active ingredient.

In some embodiments, the composition of the disclosure comprises a same type of MOMP-t-NLP. In some embodiments, the composition can comprise more than one type of MOMP-t-NLP presenting different combination of MOMP, MOMP fragments, Pmps, adjuvants and/or other components, and/or presenting a same or different combination of MOMP, MOMP fragments, Pmps, adjuvants and/or other components at different ratios, as will be understood by a skilled person.

In some embodiments, MOMP-t-NLP can be included in pharmaceutical compositions (e.g. a vaccine) together with an excipient or diluent. In particular, in some embodiments, pharmaceutical compositions are described which contain MOMP-t-NLP, in combination with one or more compatible and pharmaceutically acceptable vehicle, and in particular with pharmaceutically acceptable diluents or excipients.

The term “excipient” as used herein indicates an inactive substance used as a carrier for the active ingredients of a medication. Suitable excipients for the pharmaceutical compositions herein disclosed include any substance that enhances the ability of the body of an individual to absorb the NLP. Suitable excipients also include any substance that can be used to bulk up formulations with NLP to allow for convenient and accurate dosage. In addition to their use in the single-dosage quantity, excipients can be used in the manufacturing process to aid in the handling of NLP. Depending on the route of administration, and form of medication, different excipients may be used. Exemplary excipients include but are not limited to antiadherents, binders, coatings disintegrants, fillers, flavors (such as sweeteners) and colors, glidants, lubricants, preservatives, sorbents.

The term “diluent” as used herein indicates a diluting agent which is issued to dilute or carry an active ingredient of a composition. Suitable diluents include any substance that can decrease the viscosity of a medicinal preparation.

In certain embodiments, compositions and, in particular, pharmaceutical compositions can be formulated for systemic administration, which includes parenteral administration and more particularly intravenous, intradermic, and intramuscular administration. In some embodiments, compositions and, in particular, pharmaceutical compositions can be formulated for non-parenteral administration and more particularly intranasal, intratracheal, vaginal, oral, and sublingual administration.

In some embodiments, the compositions herein described are administrated to humans or animals via mucosal vaccination routes. The compositions can be delivered to a subject through oral mucosa or intranasal inhalation, allowing a direct absorption into the systemic circulation.

Exemplary compositions for parenteral administration include but are not limited to sterile aqueous solutions, injectable solutions or suspensions including MOMP-t-NLPs. In some embodiments, a composition for parenteral administration can be prepared at the time of use by dissolving a powdered composition, previously prepared in a freeze-dried lyophilized form, in a biologically compatible aqueous liquid (distilled water, physiological solution or other aqueous solution).

The term “lyophilization” (also known as freeze-drying or cryodesiccation) indicates a dehydration process typically used to preserve a perishable material or make the material more convenient for transport. Freeze-drying works by freezing the material and then reducing the surrounding pressure and adding enough heat to allow the frozen water in the material to sublime directly from the solid phase to gas.

If a freeze-dried substance is sealed to prevent the reabsorption of moisture, the substance may be stored at room temperature without refrigeration, and be protected against spoilage for many years. Preservation is possible because the greatly reduced water content inhibits the action of microorganisms and enzymes that would normally spoil or degrade the substance.

Lyophilization can also cause less damage to the substance than other dehydration methods using higher temperatures. Freeze-drying does not usually cause shrinkage or toughening of the material being dried. In addition, flavours and smells generally remain unchanged, making the process popular for preserving food. However, water is not the only chemical capable of sublimation, and the loss of other volatile compounds such as acetic acid (vinegar) and alcohols can yield undesirable results.

Freeze-dried products can be rehydrated (reconstituted) much more quickly and easily because the process leaves microscopic pores. The pores are created by the ice crystals that sublimate, leaving gaps or pores in their place. This is especially important when it comes to pharmaceutical uses. Lyophilization can also be used to increase the shelf life of some pharmaceuticals for many years.

In pharmaceutical applications freeze-drying is often used to increase the shelf life of products, such as vaccines and other injectables. By removing the water from the material and sealing the material in a vial, the material can be easily stored, shipped, and later reconstituted to its original form for injection.

In some embodiments, MOMP-t-NLPs herein described can be used as an immunostimulatory particle and in particular as immunostimulatory particles directed to obtain an immunitary response against one or more bacteria of the genus Chlamydia.

The term immunostimulatory as used herein describes the stimulation of the immune system and in particular the ability of a compound, complex and/or particle to affect the immune system.

The immunostimulatory MOMP-t-NLPs herein described are configured to present MOMP as an immunological agent on the t-NLP alone or together with other immunological agents such as other antigens or single or multiple adjuvants. In preferred embodiments the immunostimulatory-MOMP-t-NLPs herein described comprise MOMPS primarily forming homo-trimers in effective amount to elicit an immunological response [3].

The term “immunological agent” as used herein indicates a compound that is able to interfere with the immune system of an individual, and in particular provoke, reduce, enhance or impair a response of the immune system under same or comparable conditions. Exemplary immunological agents comprise antigen and adjuvants.

The term “antigen” or “immunogen” as used herein indicates a substance that prompts the generation of antibodies and/or can cause an immune response. In particular, antigens in the sense of the present disclosure encompass all substances that can be recognized by an adaptive immune system. Exemplary antigens include exogenous antigens and endogenous antigens. Exogenous antigens are antigens that have entered the body from the outside, for example by inhalation, ingestion, or injection. By endocytosis or phagocytosis, these antigens are taken into the antigen-presenting cells (APCs) and processed into fragments. APCs then present the fragments to T helper cells (CD4⁺) by the use of class II histocompatibility molecules on their surface. Some T cells are specific for the peptide: MHC complex. They become activated and start to secrete cytokines. Cytokines are substances that can activate cytotoxic T lymphocytes (CTL), antibody-secreting B cells, macrophages, and other particles. Endogenous antigens are antigens that have been generated within the cell, as a result of normal cell metabolism, or because of viral or intracellular bacterial infection or transformation of cells leading to cancer. The fragments are then presented on the cell surface in the complex with MHC class I molecules. If activated cytotoxic CD8⁺ T cells recognize them, the T cells begin to secrete various toxins that cause the lysis or apoptosis of the infected cell. In order to keep the cytotoxic cells from killing cells just for presenting self-proteins, self-reactive T cells are deleted from the repertoire as a result of tolerance (also known as negative selection). They include xenogenic (heterologous), autologous and idiotypic or allogenic (homologous) antigens. Antigens are also generated between normal cells.

In some embodiments, the immunostimulatory MOMP-t-NLPs herein described comprise an immunogenic fragment of the MOMP protein or MOMP immunogenic fragment. The term “immunogenic fragment” as used herein refers to a fragment of a protein that is capable of eliciting a specific immune response, such as an epitope for a B-cell or T-cell as will be understood by a skilled person. In particular, in embodiments herein described a MOMP immunogenic fragment is a MOMP fragment in the sense of the disclosure comprising an immunogenic region including immunogenic MOMP domains in addition to a transmembrane region comprising MOMP hydrophobic amino acid configured to interact with a membrane lipid bilayer. In particular, in a MOMP immunogenic fragment the immunogenic region can be formed by one or more of the variable domains and/or one or more of the epitopes of the MOMP protein, having 1 to 100 amino acid residues each.

Reference is made in this connection to the illustration of FIG. 1A, which shows exemplary variable domains (residues circled) and exemplary transmembrane domains (residues within squares) of MOMP protein. In particular FIG. 1A shows Protein sequence of major outer membrane protein (MOMP), chlamydia tracomatis, serovar C LPVGNPAEPSLMIDGILWEGFGGDPCDPCTTWCDAISMRVGYYGDFVFDRVLKTDVNK EFQMGAAPTTSDVAGLQNDPTINVARPNPAYGKHMQDAEMFTNAAYMALNIWDRFDV FCTLGATTGYLKGNSASFNLVGLFGTKTQSSSFNTAKLIPNTALNEAVVELYINTTFAWS VGARAALWECGCATLGASFQYAQSKPKVEELNVLCNASEFTINKPKGYVGAEFPLNITA GTEAATGTKDASIDYHEWQASLALSYRLNMFTPYIGVKWSRVSFDADTIRIAQPKLAEAI LDVTTLNRTTAGKGSVVSAGTDNELADTMQIVSLQLNKMKSRKSCGIAVGTTIVDADK YAVTVEARLIDERAAHVNAQFRF (SEQ ID NO: 66)

Reference is also made to the illustration of FIGS. 1B and 1C showing MOMP variable domains (herein also VD) in schematic illustration of MOMP tridimensional structure from Feher et al. [1] 2013 (see FIG. 4) incorporated herein by reference in its entirety.

Reference is also made to the illustration of FIG. 1D showing a MOMP multiepitope described in Tu et al. 2013 [2] incorporated herein by reference in its entirety; the MOMP multiepitope is expected to be comprised in MOMP immunogenic fragments herein described fused to a MOMP transmembrane region in the sense of the disclosure.

The term “epitope” as used herein, also known as an “antigenic determinant” refers to the part of an antigen that is recognized by the immune system, specifically by antibodies, B cells, or T cells. For example, the epitope is the specific piece of the antigen to which an antibody binds. The part of an antibody that binds to the epitope is called a paratope. Although epitopes are usually non-self proteins, sequences derived from the host that can be recognized (as in the case of autoimmune diseases) are also epitopes.

As a person skilled in the art would understand, the epitopes of protein antigens are divided into two categories, comprising conformational epitopes and linear epitopes, based on their structure and interaction with the paratope. A conformational epitope is composed of discontinuous sections of the antigen's amino acid sequence. These epitopes interact with the paratope based on the 3-D surface features and shape or tertiary structure of the antigen. By contrast, linear epitopes interact with the paratope based on their primary structure. A linear epitope is formed by a continuous sequence of amino acids from the antigen.

For example, T cell epitopes are presented on the surface of an antigen-presenting cell, where they are bound to MHC molecules. In humans, antigen-presenting cells are specialized to present MHC class II peptides, whereas most nucleated somatic cells present MHC class I peptides. T cell epitopes presented by MHC class I molecules are typically peptides between 8 and 11 amino acids in length, whereas MHC class II molecules present longer peptides, 13-17 amino acids in length, and non-classical MHC molecules also present non-peptidic epitopes such as glycolipids.

Epitopes can be mapped, for example using protein microarrays, or with ELISA or ELISPOT techniques, among others known to those skilled in the art. Another technique involves high-throughput mutagenesis, an epitope mapping strategy developed to improve rapid mapping of conformational epitopes on structurally complex proteins [8]. In addition, MHC class I and II epitopes can be predicted by computational means [9]. Additional methods for identifying epitopes are described in U.S. Pat. Nos. 8,889,142, 8,486,411, 7,754,228 and 6,635,746 and will be understood by a person skilled in the art.

In particular, an immunogenic fragment of MOMP refers to a fragment of a MOMP protein that is capable of eliciting a Chlamydia specific immune response in a host. As would be understood by persons skilled in the art, an immune response in a host is typically mediated by recognition by the host immune system of a specific protein epitope.

Mapping of MOMP B-cell epitopes recognized by antibodies elicited by immunization can be performed following techniques known in the art, such as those described in Tifrea et al. 2014 [10]. Examples of MOMP immunogenic epitopes comprise those of epitopes within MOMP variable domains (VD) VD1, VD2, or VD4, or constant domain (CD) CD2, CD3, CD4, or CD5; the sequences of oligomer peptide probes used to detect the epitopes and the corresponding MOMP protein domains recognized are shown in Table 2.

Additional exemplary immunogenic MOMP peptide fragments and epitopes of C. trachomatis are identifiable by those skilled in the art, in published articles such as in [2, 11-14], among others, and such as those described in U.S. Pat. Nos. 8,889,142, 8,486,411, 7,754,228 and 6,635,746.

Identification of MOMP epitopes can also be determined in part by analysis of structure of MOMP proteins. Exposed domains of MOMP are understood to be both serotyping and protective antigenic determinants [12]. The four topological models of MOMP, corresponding to C. muridarum and the C. trachomatis serovars C, D and F, have been proposed and can be used in the protein structural analysis [1, 15-17].

The immunostimulatory MOMP-t-NLP herein described can further comprise adjuvants.

The term “adjuvant” as used herein indicates an agent that stimulates the immune system but that is not antigenic in itself. Typically, adjuvants are used in connection with antigens and/or vaccine composition to increase the response to one or more antigen of choice.

Exemplary adjuvants that can be incorporated into an NLP herein described as a self-assembling component comprise; naturally occurring hydrophobic or amphipathic adjuvants, including but not limited to lipopolysaccharides (LPS), mono-phosphorylated Lipid A (MPLA), organic compounds (squalene, soribitol oleate esters), alpha-galactosyl ceramide, and lipotichoic0 acid (LTA), or hydrophilic adjuvants synthetically appended with a hydrophobic moiety, including for example microbial derivatives (e.g. CpG motifs, muramyl dipeptide (MDP), flagellin), plant derivatives (e.g. saponins), and immunostimulatory proteins (e.g. cytokines, toxins, and derivative peptides), and immunostimulatory carbohydrates and polysaccharides.

In particular, in some embodiments, immunostimulatory MOMP-t-NLP herein described present MPLA alone or in combination with additional adjuvants. MLPA is a well-established adjuvant that has been shown to induce both cellular and humoral immune responses. MPLA is a low toxicity derivative of a bacterial cell wall component, lipopolysaccharide (LPS).

In any of the above embodiments, one or more additional same or different adjuvant and/or antigen can be attached to the immunostimulatory MOMP-t-NLPs through binding the anchor compound-anchor substrate compound and/or through incorporation of an amphipathic adjuvant into the nanoparticle during self-assembly.

In some embodiments, binding or conjugation of the adjuvant or other immunological agent can be performed by chelation of the immunological agent to a functional group presented by one or more functionalized lipids in the MOMP-t-NLPs herein described. The term “chelation” as used herein indicates the binding or complexation of a bi- or multidentate ligand with a single metal ion. In particular, in some embodiments, the bi or multidentate ligand is part of the lipid and is capable of binding a metal ion. The ligands, which are often organic compounds, are called chelants, chelators, chelating agents, or sequestering agents. Chelating agents form multiple bonds with a single metal ion. The term “chelants” as used herein indicates a molecule that forms a stable complex with certain metal ions. Examples of chelating moieties include, but are not limited to, nitrilotriaceticacid (NTA), iminodiacetic acid (IDA), and diethylenetriamine penta-acetic acid (DTPA).

Successful binding of an immunological agent to the NLP can be readily verified and quantified through a range of techniques that include but are not limited to centrifugal filtration, size exclusion chromatography, fluorescence correlation spectroscopy, cantilever-based sensing, force spectroscopy, Fourier transform infrared spectroscopy, surface plasmon resonance, total internal reflection fluorescence, Raman spectroscopy and additional techniques identifiable by a skilled person. In addition, binding specifically to the surface can be verified using atomic force microscopy and transmission electron microscopy and additional techniques identifiable by a skilled person.

In some embodiments, the formation of immunostimulatory MOMP-t-NLPs herein described is amenable to the incorporation of multiple adjuvants, including for example compounds directed to enhance immune response e.g. non-human lipoproteins, bacterial peptides, DNA (e.g. CpG motifs), chemokines, cytokines, pattern-recognition receptors (PRR), lipids, polysaccharides, lipopolysaccharides, and the like; in general, agonists and immune stimulatory molecules, synthetic or natural, (known or unknown at this time) can be assembled in or on NLPs, providing for enhanced, specific, rapid immune stimulation at the site of NLP/antigen inoculation and spreading systemically.

In some embodiments, the formulated MOMP t-NLPs with single or multiple adjuvant result in a sustained IgG titer that are several logs higher than adjuvant-NLPs or NLPs alone. Adjuvants concentrations can be varied up to 20 μg per dose. In preferred embodiments, MOMP t-NLPs can comprise two or more adjuvants to provide MOMP t-NLPs capable of eliciting an optimal protective response with MOMP.

In some embodiments, immunostimulatory MOMP-t-NLPs herein described can be comprised of immunostimulatory compositions, including vaccines to be administered to individuals.

The term “individual” as used herein in the context of treatment includes a single biological organism, including but not limited to, animals and in particular higher animals and in particular vertebrates such as mammals and in particular human beings

The immunostimulatory MOMP-t-NLPs or the immunostimulatory composition herein described can also be administered to an individual alone or in combination with additional immunostimulatory agents to immunize the individual.

In particular, in some embodiments, MOMP-t-NLPs herein described can be used in combination with NLPs comprising an adjuvant such as microbial derivatives (e.g. CpG derivatives, MPLA), muramyl dipeptide derivatives (e.g. muroctasin), and any peptide or protein adjuvants (e.g. flagellin) can be incorporated into NLP directly to create an adjuvant NLP that can be used as an adjuvant or as a platform for subunit vaccine development with enhanced potency.

In particular, an adjuvant NLP according to the present disclosure can comprise single or multiple adjuvants, such as CpGs, MPLA, and cytokines. In some embodiments, an adjuvant NLP can be customized by including for example selected adjuvants in view of the desired effect based on the ability of different adjuvants to target different toll-like receptors (TLR) for immunostimulation (e.g. MPLA targets TLR 4, CpGs target TLR9, and flagellin targets TLR5). In some of these embodiments, the customization is performed in view of a specific vaccine formulation to be used in combination with the adjuvant NLP. The customization can be made to combine in the NLP only the adjuvants that are effective for the vaccine formulation of choice, since in some vaccine formulations only certain adjuvants are successful at enhancing the efficacy of the vaccine.

In some embodiments, the MOMP-t-NLP herein described are provided in a formulation compatible with intramuscular or intranasal administration in an amount effective to elicit a protective response. In some embodiments, the MOMP-t-NLP herein described are provided in a formulation for intravaginal administration in an amount effective to elicit a protective response by vaginal exposure to a Chlamydia pathogen.

Immunization can be affected by simple intramuscular injection in either the shoulder area or in the gluteus maximus hind muscular region. Particles could be delivered following solubilization in sterile normal saline solution, for example. Such immunizations would be subject to practices and methods approved by the US government Food and Drug Administration (FDA).

In particular, in some embodiments, the immunostimulatory NLPs that comprise at least one antigen can be used as vaccines that can be prepared rapidly and are relatively stable affording the desired protective immune response in accordance with attached immunogen.

The term “vaccine” as used herein indicates a composition, and in particular a biological preparation, that establishes or improves immunity to a particular external pathogenic assault, or an inherent transformational incident resulting in a cancerous or autoimmune condition in mammals. Vaccines in the sense of the present description can be prophylactic, or therapeutic.

In some embodiments, the immunostimulatory MOMP-t-NLP construct is more immunogenic than the antigen alone, and can be used as a vaccine to protect against Chlamydia infection when injected into an appropriate recipient with or without the aid or use of an adjuvant type carrier.

In particular, in some embodiments, methods herein described allow production of a functional MOMP protein in immunostimulatory MOMP-t-NLPs for vaccine development despite MOMP poor solubility, low yield, and protein misfolding which characterize MOMP production thus provide immunogenic MOMP or fragment thereof in particular in the preferred and most preferred embodiments herein described as will be understood by a skilled person upon reading of the present disclosure. The dimension and complexity of MOMP renders it difficult to recombinantly synthesize in a correctly folded state. For example, efforts to express MOMP in bacterial systems have yielded poor results due to incorrect MOMP protein folding [15, 18, 19]. In addition, processes of extracting native MOMP from Chlamydia is laborious and is difficult to produce for large-scale commercial applications. Experimental MOMP vaccines based on denatured or non-native recombinant preparations have shown to yield only partial protection in a mouse model using C. muridarum [10, 20-22].

The cell-free expression methods and systems described herein can produce a MOMP-tNLP complex with the tNLP membrane-bound MOMP forming multimers similar to the native protein in high yield, with increased solubility (Example 2), and retained functionality and immunogenicity (Examples 5-7), while eliminating the need to overexpress insoluble MOMP proteins in cells or to reconstitute MOMP with detergent. The process described herein can also be applied to other membrane-bound proteins previously difficult to obtain antigens in vivo or difficult to produce in native higher order structures.

In several embodiments, the immunostimulatory MOMP-t-NLP presenting antigens alone or in combination with adjuvants conjugates encapsulate key requirements for vaccine formulation: non-virulence; immunostimulation; clustered antigen presentation; expression of MOMP in multimeric form required for effective immune response; simple, rapid, inexpensive production; and the means to accommodate a wide range of select-agent antigens. Furthermore, adjuvant-bearing NLPs promote both humoral and cellular immune responses.

In some embodiments, the immunostimulatory MOMP-t-NLP presenting antigens alone or in combination with adjuvants in a vaccine for treating or preventing a Chlamydia infection or conditions associated thereto via intramuscular or intranasal administration. In some embodiments, the immunostimulatory MOMP-t-NLP presenting antigens alone or in combination with adjuvants in a vaccine for treating or preventing a Chlamydia infection or conditions associated thereto via intravaginal administration.

In several embodiments, the immunostimulatory MOMP-t-NLP are herein described and related compositions, methods and systems allow cost effective and rapid development of immunostimulatory compositions that are safe, enable immunization with multivalent/or broad-spectrum response and at the same time, are able to elicit a high levels protection following an adequate stimulation of a host immune response.

In several embodiments, the immunostimulatory MOMP-t-NLP, methods and systems herein described allow incorporation in the immunogenic particles of secondary additives to enhance immune response in the individual.

In certain embodiments, an adjuvant and one or more immunostimulatory MOMP-t-NLP can also be comprised in a system to immunize an individual. In those embodiments, the system comprises: the immunostimulatory particle herein described and an adjuvant, the immunostimulatory particle and the adjuvant to be administered to the individual to immunize such individual.

The systems herein disclosed can be provided in the form of kits of parts. In kit of parts for the production of MOMP-t-NLPs herein described, the MOMP and the scaffold protein can be included in the kit as a protein alone or in the presence of lipids/detergents for transition into nano-particles. The MOMP and/or the scaffold protein can be included as a plasmid or PCR DNA product for transcription/translation. The indicator protein may be included as encoded RNA for translation. In kit of parts for the immunization of an individual the immunostimulatory MOMP-t-NLP can be comprised together with adjuvant and/or adjuvant NLPs and additional components identifiable by a skilled person.

In a kit of parts, a polynucleotide, amphipathic lipid, target protein and/or scaffold protein, MOMP-tNLPs, adjuvants, adjuvant NLPs and additional reagents are comprised in the kit independently possibly included in a composition together with suitable vehicle carrier or auxiliary agents. For example, a polynucleotide can be included in one or more compositions alone and/or included in a suitable vector, and each polynucleotide in a composition together with a suitable vehicle carrier or auxiliary agent. Furthermore, the target protein can be included in various forms suitable for appropriate incorporation into the NPL.

Additional components can include labeled polynucleotides, labeled antibodies, labels, microfluidic chip, reference standards, and additional components identifiable by a skilled person upon reading of the present disclosure. In particular, the components of the kit can be provided, with suitable instructions and other necessary reagents, in order to perform the methods here disclosed. The kit will normally contain the compositions in separate containers. Instructions, for example written or audio instructions, on paper or electronic support such as tapes or CD-ROMs, for carrying out the assay, will usually be included in the kit. The kit can also contain, depending on the particular method used, other packaged reagents and materials (i.e. wash buffers and the like).

Further details concerning the identification of the suitable carrier agent or auxiliary agent of the compositions, and generally manufacturing and packaging of the kit, can be identified by the person skilled in the art upon reading of the present disclosure.

EXAMPLES

The methods and system herein disclosed are further illustrated in the following examples, which are provided by way of illustration and are not intended to be limiting.

In particular, mMOMP-tNLPs comprising a MoPn MOMP protein (mMOMP, a type of MOMP expressed in the mouse-specific Chlamydia muridarum), scaffold protein Δ49apolipoprotein A1 (Δ49ApoA1, a truncated version of mouse ApoA1), membrane-forming lipids, and telodendrimers were prepared using a cell-free expression system and characterized in vitro and in vivo. The mMOMP-tNLP particle also accommodated the co-localization of the CpG adjuvant ODN1826 for in vivo characterization. A skilled person will be able to use the membrane forming lipids, telo-dendrimers, scaffold proteins, adjuvant, and mMOMP herein described. The following materials and methods were used.

Plasmids:

The truncated form of mouse Apo A1 (Δ1-49) or Δ49ApoA1 gene and mMOMP gene were assembled from oligonucleotides and cloned into NdeI/BamHI digested pIVEX2.4d vector (Roche Molecular Diagnostics, Basel, Switzerland) using Gibson Assembly. Briefly, Archetype Software was used to design 60 bp long, overlapping oligonucleotides covering the DNA sequence of interest (Δ49ApoA1 including 90 bp 5′ and 3′ vector overlap to pIVEX2.4d). The 60 bp oligonucleotides overlapped neighboring oligonucleotides by 30 bp. In addition, forward and reverse primers (distal primers) were designed for amplification of the DNA sequence of interest. The pIVEX2.4d vector contained a His-tag used for nickel affinity purification as previously described [23]. The codon-optimized plasmid sequences are shown (FIG. 3; also shown in FIGS. 12A-C, 13, 14, 15, 16 and 17).

DMPC/Telodendrimer Preparation:

PEG^(5k)-CA telodendrimer was prepared according to a published method [24]. Small unilamellar vesicles of DMPC (Avanti Polar Lipids, Alabaster, Ala.) were prepared by probe sonication of a 20 mg/mL aqueous solution of DMPC until optical clarity was achieved; typically 3 intervals of 30 seconds were sufficient. After the sonication, the samples were centrifuged at 14,100 rcf for 1 minute to remove metal contamination from the probe tip. For the DMPC/PEG^(5k)-CA₈ mixtures, a total of 20 mg/mL DMPC and 2 mg/mL PEG^(5k)-CA₈ were mixed at a volume ratio of 1:1.

Cell-Free Reaction:

Small and large scale reactions (50 μL and 1 mL) were carried out using RTS 500 ProteoMaster E. coli HY Kit (Biotechrabbit GmbH, Hannover, Germany). Small scale reactions contained the same ratio of components as the large-scale reactions. Reaction components (lysate, reaction mix, feeding mix, amino acid mix, and methionine) were combined as specified by the manufacturer. For expression, 0.3-1.5 μg of Δ49ApoA1 and 15 μg mMOMP plasmid DNA was added to each 1 mL reaction. A total of 400 μL DMPC/telodendrimer mixture was then added. The reactions were incubated at 30° C., with shaking at 300 rpm for 14-18 hrs in a floor shaker.

Affinity Purification of NLP-Related Complexes:

Immobilized nickel affinity chromatography was used to isolate the mMOMP-tNLP from the cell-free reaction mixture. 1 mL of 50% slurry cOmplete His-Tag Purification Resin (Roche Molecular Diagnostics, Basel, Switzerland) was equilibrated with equilibration buffer (50 mM NaH₂PO₄, 300 mM NaCl, pH 8.0) with 10 mM imidazole (Sigma-Aldrich, St Louis, Mo.) in a 10 mL chromatography column. The total cell free reaction (1 mL) was mixed with the equilibrated resin, and was incubated/nutated at 4° C. for 1 hr. The column was then washed with equilibration buffer containing 20 mM imidazole. The column was washed with 1 mL of the same buffer 6 times. The mMOMP-tNLPs were eluted in six 300 μl fractions of equilibration buffer containing 250 mM imidazole and 1 final elution of 300 μl in 500 mM imidazole. All elutions were analyzed by SDS-PAGE and peak fractions containing protein were combined. Pooled fractions were dialyzed in PBS (pH 7.4) and then stored at 4° C. Material for mouse studies were tested for endotoxin levels using the Endosafe-PTS (Charles River, Charleston, S.C.) endotoxin testing system based on Limulus Amebocyte Lysate (LAL) assay. All NLP preparations have an endotoxin level between 20 and 100 EU/mg.

Size Exclusion Chromatography (SEC):

NLPs were purified by SEC (Superdex 200, 10/300 GL column, GE Healthcare, Piscataway, N.J.). SEC was run at a flow rate of 1 mL/min in PBS buffer with 0.25% PEG2000.

SDS Page:

A total of 5-15 μL aliquots of the eluted mMOMP-tNLPs were mixed with 4× NuPAGE LDS Sample buffer and 10× NuPAGE Sample Reducing Agent (Life Technologies Corporation, Carlsbad, Calif.), heat denatured and loaded onto a 4-12% gradient pre-made 1.0 mm Bis-Tris gel (Life Technologies Corporation, Carlsbad, Calif.) along with the molecular weight standard SeeBlue Plus2 (Life Technologies Corporation, Carlsbad, Calif.). The running buffer was 1×MES-SDS (Life Technologies Corporation, Carlsbad, Calif.). Samples were run for 35 minutes at 200V. Gels were stained with SYPRO Ruby Protein Gel stain (Life Technologies Corporation, Carlsbad, Calif.) according to manufacturer's instructions, and imaged using a LiCor Odyssey Fc Imager (LI-COR Biotechnology, Lincoln, Nebr.).

Western Blots and Dot Blots Analysis:

Western and dot blots were performed on PVDF membranes (Millipore). For western blots, samples were resolved with SDS-PAGE as described above. The gels were incubated in transfer buffer for 10 minutes and transferred at 4° C. for 65 minutes at 100V. The transfer buffer was 1× NuPAGE (Life Technologies Corporation, Carlsbad, Calif.). Blots were incubated overnight at 4° C. in Odyssey Blocking Buffer (PBS) (LiCor Biotechnology, Lincoln, Nebr.) containing 0.2% Tween-20 and either 0.5 mg/mL mAb40 (linear, VD1) or 0.2 mg/mL Penta-His antibody (Qiagen, Hilden, Germany) diluted 1:1000 [25]. Blots were then washed for five minutes, four times, with PBS-T (50 mM NaH₂PO₄, 300 mM NaCl, 0.2% Tween-20, pH 7.4) while shaking. Blots were then incubated for 1 hour in blocking buffer containing 0.2% Tween-20, 0.02% SDS and 1 mg/mL IRDye 800CW Goat (polyclonal) anti-Mouse IgG (H+L) (LI-COR Biosciences, Lincoln, Nebr.) diluted to 1:10,000. Blots were washed with PBS-T four more times and imaged with LiCor Fc Imager at 800 nm. For dot blots, 3 μg of purified nanoparticles with and without mMOMP were blotted using the Bio-Dot Apparatus #1706545 (Bio-Rad), according to manufacturer's instructions. Blots were developed as mentioned above.

Conductance Assays:

To look at the ability of mMOMP to form functional pores, the mMOMP-tNLP complex was incorporated into planar lipid bilayer and conductance measurements were performed in a two-chamber black lipid membranes (BLM) cell (Eastern Scientific LLC, Rockville, Md., USA). A supported DMPC lipid bilayer was formed over a 200 μm diameter aperture in a Teflon film partition using a painting technique. The cis-chamber (connected to ground Ag/AgCl electrode) and trans-chamber (connected to a reference Ag/AgCl electrode) were filled with 0.2 mL and 2 mL PBS buffer (w/Mg²⁺ and Ca²⁺, pH 7.4) respectively. 1-2 μL mMOMP-tNLP complex in solution was added to the cis-chamber above the DMPC bilayer. A holding potential between −100 mV to +100 mV was applied to the reference electrode, and the transmembrane current signal was recorded by the Axiopatch 200B patch clamp amplifier (Axon Instruments, Milpitas, Calif., USA) connected to a computer system running Clampex 10.3 software (Axon Instruments). The current traces were acquired at a sampling frequency of 10 kHz-100 kHz. The data were exported and analyzed using PClamp 10.3 software (Axon Instruments) and Igor Pro 6.31 (Wavemetrics Inc.).

Dynamic Light Scattering (DLS):

Dynamic light scattering measurements of the NLP size were performed on a Zetasizer Nano ZS90 (Malvern Instruments, Malvern United Kingdom)) following the manufacturer's protocols. Each data point represents an average of at least 10 individual runs.

Atomic Force Microscopy (AFM):

AFM is a technique known to a skilled person to investigate NLPs and membrane protein insertion¹⁴⁵⁻¹⁴⁸. Briefly, atomically flat mica disks are glued to metal substrates to secure them to the scanner of a stand-alone MFP-3D AFM (Asylum Research, Santa Barbara, Calif.). Topographical images are obtained with “Biolevers” (Olympus, Tokyo, Japan) with a spring constant of 0.03 N/m in a room temperature controlled room at 23+/−1° C. Images are taken in alternate contact (AC) mode in liquid, with very low amplitudes at the primary resonance frequency that was obtained from thermal analysis of the cantilever in solution. Heights of features in images are determined by histogram and statistical analysis as will be understood by a skilled person^(60,112,113).

Transmission Electron Microscopy (TEM):

Samples are harvested using both continuous carbon coated TEM grids and small silicon wafers with silicon nitride membranes (each ˜3 mm in diameter). For NLP samples, a 4 μL drop of the purified sample (0.5 mg/ml) can be adsorbed to a cleaned holey-carbon-coated copper EM grid, blotted with Whatman paper and rapidly plunge frozen. The resulting cryoEM grid can then be imaged using low-dose exposure techniques on a JEOL JEM-2100F transmission electron microscope. Electron micrographs are direct images of the sample, acquiring a large dataset provides a statistical overview of the homogeneity and aggregation of the protein or complex in solution¹⁴⁹⁻¹⁵¹

Cryo-Electron Microscopy (cryoEM):

In cryoEM, a fully hydrated complex is frozen and then subjected to electron microscopy. This permits an advantage in studying hydrated complexes used for detailed and accurate image re-construction¹⁵²⁻¹⁵⁷ All tNLP and mMOMP-tNLP samples were preserved as frozen hydrated specimen in the presence of saturated ammonium molybdate for scanning with a JEOL JEM-2100F transmission electron microscope (JOEL USA, Peabody, Mass.) at magnification of 80,000× under liquid nitrogen temperature.

Mouse Immune Study:

All animal studies were performed at Lawrence Livermore National Laboratory in PHS-assured facilities in accordance with guidelines set by the Animal Care and Use Committee (IACUC). Female 3-week old mice (BALB/c) were purchased from Jackson Laboratory (Bar Harbor, Me.). Since 3-week old mice are pre-pubescent, they are more susceptible to STI infection and more suitable than adult mice for the Chlamydia studies. A total of 6 mice/group were vaccinated with the following formulations: 1×10⁴ IFU's of EB obtained from Dr. Luis de la Maza at UC Irvine, 10 μg of tNLP with 5 μg CpG adjuvant, 10 pig mMOMP-tNLP plus 5 μg of CpG adjuvant, or PBS alone. Total volumes per inoculation were 50 μL. Animals were primed on day 1 and received boosts at days 21 and 42. Whole blood was drawn prior to each inoculation. A final bleed was conducted on day 61 post initial prime. Serum antigen specific IgG antibody titers were measured using an enzyme-linked immunosorbent assay (ELISA). Immulon 2HB microtiter plates (Thermo Labsystems, Franklin, Mass.) were coated with the appropriate antigen (200 ng/well), and then incubated with sera (2-fold serial dilutions starting at 1:100 dilutions) for 1 hour. Goat anti-mouse IgG HRP-conjugated antibody (KPL, Gaithersburg, Md.) was added to the plates for 1 hour, and the bound HRP was detected by incubation with TMB (Sigma) quenched after 5 min with 1 M HCl. The reaction product was quantitated by a spectrophotometer at 450 nm, and values were corrected for background activity detected from wells that received diluent in place of sera. The titration curves were then fit to a power function in MS Office Excel and titers were calculated from the fit function using a cutoff absorbance value of the average background O. D.±3 S. D.

Example 1. Structural Characterization of Native MOMP

A structural characterization of MOMP was performed with TEM.

In particular, the TEM analysis performed shows monodispersed native MOMP (FIG. 23A) stained with 5% ammonium molybdate and placed on continuous carbon grids for observation. For model building, trimeric MOMP particles are selected using a semi-automated particle selection tool via EMAN 2.1 package [26] (FIG. 23B). The pre-processing of MOMP image analysis shows that the protein is predominantly in a trimeric association, with some sample heterogeneity

MOMP trimer images were then collected and class averaged. The individual MOMP trimer images were processed using reference-free classification to group particles with similar orientation (FIG. 23C). The images were then aligned, rotated, and averaged.

Preliminary Raw projection images show clear trimeric association and distinct features of MOMP (FIG. 23D). In particular, in the illustration of FIG. 23D, raw projection images of MOMP trimer show distinct structural features (white arrow). The diameter of the MOMP trimer was calculated to be 90 Angstroms.

Furthermore, preliminary 3D density maps were generated for comparison to MOMP from Campylobacter jejuni (Protein Data Base (PDB) ID: 5LDT)[27] (FIG. 23E). Class averaged images can be used for comparison to previously solved MOMP structures, such as MOMP from Campylobacter jejuni (5LDT). Black arrow indicates the fitted edges of preliminary density map generated from class averages.

Example 2. Cell-Free Co-Translation Supports Soluble mMOMP Expression

Codon optimization was used to alter sequences for mMOMP-tNLP expression in E. coli cell-free lysates (FIG. 2). Codon optimization of the Δ49ApoA1 and mMOMP sequences resulted in a ˜20% change in the primary protein coding sequences for both proteins (FIGS. 3, 12C, 16 and 17). Co-translation reaction conditions using plasmids encoding Δ49ApoA1 and mMOMP were initially screened using a bodipy-lysine fluorescent amino acid to simplify visualization of protein expression and solubility screening.

The bodipy-lysine fluorescent amino acid is randomly inserted at lysine positions within the protein at a low insertion rate. The mMOMP protein is highly hydrophobic and is normally insoluble in the absence of a native lipid bilayer or detergents. Co-translation with both plasmids in the presence of DMPC lipid alone did not result in a soluble mMOMP expression product. Soluble mMOMP was observed only when the cell-free reactions were modified to include both DMPC lipid and telodendrimer PEG^(5k)-CA₈.

The solubility of mMOMP increased from 10% to 75% upon insertion into tNLP (FIG. 4). The PEGylated tail of the telodendrimer may protect the mMOMP from interacting with surrounding mMOMP-tNLPs and thus increases its solubility.

After the cell-free reaction was completed, the total cell-free mixtures were centrifuged by a table centrifuge at max speed for 10 minutes. After centrifugation, the supernatant was collected. MOMP solubility is defined by the ratio of the amount MOMP protein in supernatant to the amount of MOMP protein in the total mixture.

In order to produce soluble mMOMP 0.1 to 0.5 mg/mL of telodendrimer were provided in the cell-free reaction.

By adding plasmids encoding mMOMP and scaffolding protein ApoA1 at different ratio, the expressed ratios of mMOMP:ApoA1 and the number of mMOMP per tNLP were controlled. Typically, the concentration of plasmid encoding mMOMP in the cell-free mixture is 15 ug/mL. Plasmid encoding ApoA1 is added at a mMOMP plasmid to ApoA1 plasmid ratio of 1:1, 2:1, 5:1, 10:1, 15:1, 20:1, 50:1, 100:1, or 200:1. The expressed ratios of mMOMP:ApoA1 is assessed by SDS-PAGE. The optimal expressed ratios of mMOMP:ApoA1 is expected to be from 1:1 to 3:1. The optimal expressed ratios of mMOMP:ApoA1 is achieved by using mMOMP plasmid to ApoA1 plasmid ratio from 10:1 to 25:1. At the optimal ration, the number of mMOMP per tNLP is expected to be from 1 to 3 mMOMP per tNLP.

Reactions were scaled up to 1 mL to produce sufficient quantities of mMOMP for subsequent nickel purification utilizing the HIS tag on the apolipoprotein scaffold component of the tNLP.

The purification provided a complex that was >95% pure based on SDS-PAGE analysis. On average, a 1 mL reaction yielded 1.5 mg of purified mMOMP-tNLP (FIG. 5a ) based on gel densitometry. Distinct bands indicated that the two proteins, apolipoprotein and mMOMP, were co-purifying as a complex.

To further characterize the mMOMP-tNLP complex, individual affinity purification elution fractions were assessed by size exclusion chromatography (SEC) (FIG. 5b ). SEC analysis confirmed that each mMOMP-tNLP fraction eluted at the appropriate time (retention time (t_(r))˜7 min) without un-incorporated protein or free lipid peaks (t_(r)˜15 min and 4 min, respectively), indicating that the complex was a homogenous mixture of mMOMP-tNLPs.

Dot blots of SEC fractions demonstrated that both the apolipoprotein and mMOMP were co-localized within the peak fraction (FIG. 5c ).

Example 3. mMOMP-tNLPs Form Disc Shaped Nanoparticles

Dynamic light scattering (DLS) was used to visualize the overall size of the purified mMOMP-tNLP complex. The empty tNLPs were approximately 10 nm in diameter (FIG. 6a ). The mMOMP-tNLP particle sizes showed an almost 4-fold increase in diameter to about 40 nm (FIG. 6b ) wherein the term about when referred to length indicates ±0.5 the unit of length such as nm or Å. This large increase was unexpected, but plausible given that each mMOMP contains 16 transmembrane domains. In addition, image analysis using cryo-electron microscopy (cryoEM) indicated that mMOMP-tNLPs were disc-shaped (FIG. 6c ).

A comparison between empty tNLPs and mMOMP-tNLPs via cryoEM also confirmed the larger particle size of mMOMP-tNLPs. The cryoEM images also revealed that mMOMP-tNLPs, not empty tNLPs, contained multiple regions of enhanced density of relatively uniform size with a diameter of about 20-30 Å. Since the samples were highly purified, these regions likely represent mMOMP proteins that form pores inside a tNLP. Interestingly, although the number of mMOMP pores per tNLP particle varied, the mMOMP-tNLP particles had an average of 3 mMOMP proteins inserted.

Example 4. mMOMP Associated with tNLPs Form Higher Order Structures

Membrane-bound porins are known to be resistant to denaturant, providing a means to probing the formation of oligomer species using SDS-polyacrylamide gels [25, 28]. By analyzing mMOMP-tNLP in the presence and absence of both heat and reducing agent, higher-order oligomers of mMOMP were identified. SDS-PAGE of heated samples in the presence of DTT showed primarily two distinct bands on the gel, corresponding to mMOMP and Δ49ApoA1 at approximately 40 kD and 22 kD, respectively. However, with heat and reducing agent (DTT) removed, distinct bands corresponding to mMOMP oligomers were observed on the gel that were absent in tNLP alone control, indicating that these oligomers are part of mMOMP and not oligomers of the apolipoprotein scaffold (FIG. 7a ). These results closely resemble the gel banding pattern attributed to oligomer formation of native MOMP [28]. Western blot analysis probed with mAb40 also indicated the formation of the higher order structures of mMOMP (FIG. 7b ). These multimeric structures are not evident in recombinant MOMP produced in traditional E. coli expression systems, suggesting that the confinement to the constrained lipid bilayer of the tNLP can promote native-like oligomerization [25].

Dot blots were then tested to determine if adding both heat and reducing agent affect mMOMP antibody binding. Antibodies specific for mMOMP linear epitope detection (mAb40) with and without heat and reducing agent resulted in the same intensity of signal, indicating that the oligomers of mMOMP are broken down to monomers upon heat and DTT. Furthermore, heat and DTT do not affect the mAb40 binding to mMOMP. As a control, mAb-HIS was always able to detect the apolipoprotein supporting scaffold (FIG. 8).

Native MOMP forms dimers, trimers, and tetramers in an oxidized environment [15]. It has also been demonstrated that maintaining native MOMP structure is necessary to elicit a robust immune response [10, 19]. The results in this Example show that mMOMP supported by tNLP particles mimic native mMOMP oligomer structures. The mMOMP higher order oligomer resembles previously reported native MOMP trimers [19].

Example 5. tNLP Solubilized mMOMP Forms Functional Pores in Bilayers

Previous studies have shown that the presence of mMOMP initiates pores in lipid bilayers [15]. Therefore, we used conductance analysis to test the function of mMOMP supported in the tNLP. The pore-forming activities of mMOMP-tNLP were tested in a typical black lipid membrane channel reconstitution experiment using the single-channel recording technique [29]. Control experiments with tNLP alone did not produce channel activity under a series of applied transmembrane voltages ranging from −100 to +100 mV (FIG. 9a , trace i). However, discrete increases in current were observed 3-5 seconds after the addition of 1-2 μL of mMOMP-tNLP solution to the cis-chamber. This current increase corresponded to the bilayer pore formation by the mMOMP proteins, indicating functional mMOMP insertion (FIG. 9a , traces ii-iv). All mMOMP channel incorporation events were permanent and did not show any gating or transient blockade patterns under the conditions studied. The mMOMP-tNLP conductance was predominantly ˜172 pA at physiological condition.

The conductance change of a large number of incorporation events was plotted on a histogram (n=184, FIG. 9b ) and is consistent with the presence of two gaussian peaks at 1× and 3× multiples of a single conductance value. Interestingly, attempts to fit the histogram to a sum of three peaks at 1×, 2×, and 3× did not produce a better fit, indicating that mMOMP channel may have a tendency to oligomerize within the membrane and form trimers (corresponding to three pores).

Thus, the results of the conductance assays suggest that a population of mMOMP in the mMOMP-tNLP sample is likely to be in a functional oligomeric state in the bilayer. Accordingly, cell-free produced mMOMP appears to adopt a functional conformation, which has never been previously reported for any recombinant MOMP. Importantly, cross-linking of the recombinant protein was not required to observe oligomerization. Cell-free expression followed by direct insertion into the tNLP appears to help maintain the functional conformation of membrane bound proteins [30, 31].

Example 6. The mMOMP-tNLP Complex Elicits an IgG Response in Mice

The tNLPs (negative control) or mMOMP-tNLPs were adjuvanted with CpG and injected intramuscularly (i.m.) into mice. Additional groups of mice were injected i.m. with PBS (negative control) or Chlamydia EB (positive control). It was found that mMOMP-tNLP supports the addition of CpG adjuvant and elicits significant levels of antigen-specific antibody titers compared to CpG:tNLP (no antigen) and PBS controls (FIG. 10a ).

The formulation of mMOMP-tNLP plus CpG adjuvant results in the incorporation of the CpG adjuvant into the mMOMP-tNLP particle.

Pooled mouse sera from injected mice were then probed on a western blot to detect for specific mMOMP binding (FIG. 10b ). The sera from mice injected with mMOMP-CpG-tNLP showed strong mMOMP binding. The lane from sera immunized with Chlamydia EB also detected some mMOMP binding. It is not surprising that EB sera showed less binding than mMOMP-CpG-tNLP sera because EB contains many other proteins other than mMOMP. Therefore, there were many antibodies generated against EB and only a portion of these antibodies was mMOMP-specific. Sera from PBS and CpG:tNLP control groups showed no mMOMP binding. This Example shows that immunogenic adjuvants such as CpG can be incorporated into mMOMP-tNLP formulation.

Example 7: MOMP-NLP Complexes are Immunogenic and Protective

The protective response of MOMP-NLPs formulated with CpG, a TLR-9 agonist that elicits Th1 responses, or CpG and FSL₁ was evaluated in a mouse intranasal challenge study. (FIG. 18).

FSL₁ is a TLR-2/6 agonist that induces Th2 response. It is expected that when delivered together with antigens in the same NLP, the CpG and FSL₁ will elicit more robust protective responses than if antigens and adjuvants were simply injected simultaneously. CpG and FSL₁ can be administrated to the mouse using systemic and/or mucosal routes for immunization.

Mice were inoculated intranasally with formulated controls or different formulations of MOMP-NLPs with CpG or CpG and FSL₁ adjuvants. With chlamydial challenges, the mice undergo weight loss and recovery. The recovery is an indication of protection for any formulation.

In FIG. 18, panel A, the antibody tiers from immunized mice show antibody cross reactivity with C. muridarum MOMP (anti-MOMP) or EB (anti-EB). In FIG. 18, panel B, weight loss over time following intranasal (i.n) challenge with C. muridarum was used as a measure of protection. Data was analyzed using RM two-way ANOVA with Sidak's multiple comparison analysis.

Mice immunized with MOMP:CpG:NLPs or MOMP:CpG:FSL1:NLPs generated antibodies that recognized both MOMP and EB (FIG. 18, panel A). The MOMP:CpG:FSL1:NLP formulation with two adjuvants showed a substantial protective response in the intranasal model as compared to the other formulations (FIG. 18, panel B). Lower MOMP-specific IgG titers in the EB sample is expected because there are other antigens, such as Pmps, presented on EB than just the MOMP protein. Additionally, mice immunized with MOMP:NLP lost significant body weight by 4 days post challenge (d.p.c.) but by 10 d.p.c. have recovered most of their weight (FIG. 18, Panel B).

FIG. 18 panel C plots the number of Cm IFU recovered from mice vaccinated with different MOMP:NLPs formulations. Each dot represents a mouse. The horizontal line corresponds to the median. The number of Cm IFU recovered from mice vaccinated with MOMP:NLP was significantly less than from sham-vaccinated groups (p<0.05).

These combined preliminary results demonstrate the feasibility of extending NLP approach to the genital model for further vaccine development.

Additionally, since using systemic and/or mucosal routes for immunization, a better protection has been observed when using both routes[32, 33]. It is therefore expected that delivery of CpG-1826 and FSL-1 by both routes will result in enhancing systemic and mucosal humoral and cellular memory immune responses.

Example 8: Exemplary Chlamydia Vaccine Pipeline

NLPs provide a versatile platform for vaccine development. By combining the rapid production of functional membrane proteins with adjuvant addition and structural screening, a pipeline for vaccine generation is developed.

FIG. 19 illustrates a schematic of an exemplary Chlamydia vaccine pipeline. In particular, constituents such as DNA, lipids, cofactors and cell-free extracts are combined in a single reaction vial. The cell-free lysates utilize T7-coupled transcription and translation to produce nanoparticles complexed with the antigens and adjuvants of interest. The nanoparticles then can be characterized and administrated to mice to protect them from a chlamydial infection.

Example 9: Generation of Optimal Vaccine Formulations

In this example, experiments were carrier out to optimize the ratio of MOMP to Apolipoprotein for high-level cell-free expression, purification, and formulation of functional complexes in NLPs.

Cell-free expression technologies have demonstrated to overcome bottlenecks associated with membrane protein expression. In this example, cell-free C. muridarum MOMP have been generated in which the plasmid ratio of pApo to pMOMP was provided at 1:1, 1:5, 1:10, 1:25, 1:50, and 1:100 as shown in FIG. 20A.

FIG. 20 A shows results from the SDS-PAGE analysis following cell free synthesis of MOMP-NLPs using varying amounts of fluorescent labeled Apo and MOMP proteins. The plasmid ratio expression screening displays different levels of inserted MOMP embedded in the NLPS complex. The SDS-PAGE analysis results show that a higher ratio of MOMP to Apo leads to a higher amount of MOMP proteins incorporated in the NLPs.

Scanning electron microscopy was also used to determine average particle size of the MOMP-NLPs. FIG. 20B shows scanning electron microscopic images (SEM) of (A) empty NLP disc, (B) MOMP-NLP disc with 1-2 monomers of MOMP inserted, (C) MOMP-NLP disc with 1-2 trimers of MOMP inserted, and (D) MOMP-NLP disc 3 trimers of MOMP inserted.

The images of FIG. 20B demonstrate that the MOMP-NLP particles are disc like in shape and there are size differences among MOMP-NLP particles with varying ratios of MOMP to Apo. The higher ratios of MOMP protein inserted in the disc correlate to particles with larger disc size.

Example 10: Cell-Free Production of Polymorphic Membrane Proteins Associated with MOMP

Polymorphic membrane proteins (Pmps) are another group of surface exposed candidate antigens. C. trachomatis and C. muridarum have nine Pmp genes. Pmps are well conserved among all C. trachomatis serovars, as well as C. muridarum. Therefore, Pmps may help broaden the protective immune responses elicited by MOMP. This family of proteins is surface exposed and mediates the adhesion of Chlamydia EB to the eukaryotic host cells. The Pmp proteins are also immunogenic in humans and mice. Vaccination of mice with fragments derived from different Pmps elicits protection against both genital and respiratory challenges with C. muridarum. Based on these studies, PmpC, PmpE, PmpF, PmpG and PmpH were identified as potential protective antigens [34-38]. However, production of full-length recombinant Pmps has yet to be achieved.

In this example, experiments were carried out to engineer the expression plasmids and produce water soluble full-length and truncated C. muridarum Pmp C, E, F, G, and H using cell-free approaches described herein.

Exemplary PMP gene and protein sequences used in this study are listed in Table 3. The original sequences are retrieved from public databases such as Uniprot/SWISS-PROT or NCBI gene database as will be understood by a person of ordinary skill in the art

In a first set of experiments, codon optimization was used to alter sequences for Pmp-tNLP expression in E. coli cell-free lysates. Codon optimization of the Δ49ApoA1 or ApoE4 and Pmp sequences resulted in production of full-length protein with and without adhesion domain. Co-translation reaction conditions using plasmids encoding Δ49ApoA1 or ApoE4 and Pmp were initially screened using a bodipy-lysine fluorescent amino acid to simplify visualization of protein expression and solubility screening.

The bodipy-lysine fluorescent amino acid is randomly inserted at lysine positions within the protein at a low insertion rate. Pmp expression was observed in the cell-free reactions include both DMPC lipid and telodendrimer PEG^(5k)-CA₈. After the cell-free reaction was completed, the total cell-free mixtures were resolved by SDS-PAGE and imaged by fluorescent imaging. The plasmids encoding Pmp and scaffolding protein ApoA1 or ApoE4 is at ratio of 50:1 (FIG. 21A).

The results illustrated in FIG. 21A show SDS-PAGE images of codon-optimized fluorescent labeled Pmps (PmpC, PmpE, PmpF, PmpG, and PmpH) and truncated versions that lack the adhesion domain. These results show that full-length and truncation Pmp proteins can be cell-free expressed in the presence of lipid and telodendrimer as will be understood by a skilled person.

In a second set of experiments, co-translation reaction using plasmids encoding Δ49ApoA1 or ApoE4 and PmpH were set up in the presence of bodipy-lysine fluorescent amino acid, DMPC lipid and telodendrimer PEG^(5k)-CA₈. The plasmids encoding Pmp and scaffolding protein ApoA1 or ApoE4 is at ratio of 50:1. Reactions were scaled up to 1 mL to produce sufficient quantities of Pmp for subsequent nickel purification utilizing the HIS tag on the apolipoprotein scaffold component of the tNLP.

The purification provided a complex that was >95% pure based on SDS-PAGE analysis. On average, a 1 mL reaction produced ˜200 μg of PmpH (FIG. 21B) based on gel densitometry. Distinct bands indicated that the two proteins, apolipoprotein and Pmp, were co-purifying as a complex.

The results are illustrated in FIG. 21B which shows SDS-PAGE images of cell-free expressed and nickel-purified PmpH and Δ49 ApoA₁, a truncated version of mouse ApoA1 in which the N-terminal 49 amino acids were removed. A 1 mL reaction produced ˜200 μg of PmpH. Although in this set of experiments MOMP was not cotranslated with PmpH, MOMP can be translated with PmpH as will be understood by a skilled person upon reading of the present disclosure.

Example 11: Structural and Protective Assessment of Chlamydial Proteins

This example further demonstrates that NLPs are a vaccine delivery platform for membrane protein antigens. In addition, the example also confirms that C. muridarum MOMP is amenable to gene optimization, cell-free expression, and purification in the NLP complex.

The experiments were carried out using the approaches previously described in Examples 4 and 5. In particular, an Escherichia coli-based cell-free system was used to express a MOMP protein from the mouse-specific species Chlamydia muridarum (MoPn-MOMP or mMOMP). The codon-optimized mMOMP gene was co-translated with Δ49apolipoprotein A1 (Δ49ApoA1), a truncated version of mouse ApoA1 in which the N-terminal 49 amino acids were removed. This co-translation process produced mMOMP supported within a telodendrimer nanolipoprotein particle (mMOMP-tNLP). The cell-free expressed mMOMP-tNLPs contain mMOMP multimers similar to the native MOMP protein. This cell-free process produced on average 1.5 mg of purified, water-soluble mMOMP-tNLP complex in a 1-ml cell-free reaction.

FIG. 22 demonstrates a cell-free production of MOMP co-translated with ApoA₁ Δ49A₁. FIG. 22 panel A shows SDS-PAGE images of cell-free expressed and purified MOMP and ApoA1 Δ49A1.

FIG. 22 panel B shows exemplary results of dot blot analysis MOMP-NLP and NLP assemblies treated with heat and reducing agent. The MOMP-NLP and NLP assemblies were blotted in triplicate and probed with mAb40, mAbHIS and mAb18b. The confirmation of the MOMP trimer was confirmed using the conformational monoclonal antibody mAb18b. Addition of heat and DTT results in a decrease in signal as detected by mAb18b, indicating a loss in trimer formation. mAb40 recognizes both MOMP monomer and trimer as it binds to a linear epitope. The mAbHIS recognizes the HIS tag on the Δ49A1 protein.

FIG. 22 panel C shows conductance traces recorded at 50 mV applied voltage in physiological conditions after NLP alone and MOMP-NLP were added to the measurement chamber. Current increases observed after MOMP-NLP addition indicate the formation of bilayer pore formation by MOMP proteins, indicating functional MOMP insertion.

Using the mMOMP-tNLP formulation, a unique approach is demonstrated to solubilizing and administering membrane-bound proteins for future vaccine development. This method can also be applied to include other antigens such as Pmps while maintaining their full functionality and immunogenicity.

Example 12: Structural and Protective Assessment of Chlamydial Proteins

The experiments in this example were carried out using procedures described in Example 7.

In particular, the protective response of MOMP-NLP was evaluated in a mouse intranasal challenge study. Briefly, were inoculated intranasally with formulated controls (PBS or empty NLPs) or different formulations of MOMP-NLPs. With chlamydial challenges, the mice undergo weight loss and recovery. The recovery is an indication of protection for any formulation.

In FIG. 24, weight loss over time following intranasal (i.n) challenge with C. muridarum was used as a measure of protection. Data was analyzed using RM two-way ANOVA with Sidak's multiple comparison analysis.

In vivo vaccination with MOMP-NLPs displayed strong protection against Chlamydia challenge in mice compared to empty NLPs and PBS control. Additionally, mice immunized with MOMP:NLP lost significant body weight by 4 days post challenge (d.p.c.) but by 10 d.p.c. have recovered some of their weight (FIG. 24). The positive control, Chlamydia elementary body (EB), demonstrates complete protection.

These combined preliminary results demonstrate the feasibility of extending NLP approach to the genital model for further vaccine development.

Additionally, since using systemic and/or mucosal routes for immunization, a better protection has been observed when using both routes. It is therefore expected that delivery of MOMP-NLPs by both routes will result in enhancing systemic and mucosal humoral and cellular memory immune responses.

In summary, described herein is a telodendrimer-nanolipoprotein particle (t-NLP), comprising one or more membrane forming lipids, one or more telodendrimers, and a scaffold protein and a Chlamydia major outer membrane protein (MOMP) comprising a MOMP hydrophobic region, and related compositions methods and systems.
